The air that it traps is in contact with oxygenated water, so as the animal's consumption depletes the oxygen in the bubble, more oxygen can diffuse in to replenish it. The beetles exoskeleton is made up of numerous plates called sclerites (a hardened body part), separated by thin sutures. Major sites from the Upper Cretaceous include Kzyl-Dzhar in South Kazakhstan and Arkagala in Russia. They are adapted to almost any environment on earth except the ocean and polar ice caps. Cetonine larvae, similar to those of geotrupids and lucanids, are often short, less C-shaped than most scarabaeids, hairy, active, and capable of locomotion on their backs through movement of body segments. In some cases, however, more dramatic changes occur. It has paired inlets or ostia at intervals down its length, and circulates the hemolymph from the main cavity of the haemocoel and out through the anterior cavity in the head. Grant No. [165], Beetles can be beneficial to human economics by controlling the populations of pests. Some beetles found in dung and carrion are in fact predatory. [83] Larval morphology is highly varied amongst species, with well-developed and sclerotized heads, distinguishable thoracic and abdominal segments (usually the tenth, though sometimes the eighth or ninth). The cameras filmed over a 60 range for up to 6 hours. "Insectary Studies on the Control of Dung Breeding Flies by the Activity of the Dung Beetle, "The economic value of ecological services provided by insects", 10.1641/0006-3568(2006)56[311:TEVOES]2.0.CO;2, "U.N. Urges Eating Insects; 8 Popular Bugs to Try", "Therapeutic arthropods and other, largely terrestrial, folk-medicinally important invertebrates: a comparative survey and review", Life cycle of the rounded jewel beetles, Sternocera spp. This sport exploits the territorial behavior and mating competition of certain species of large beetles. [150] The Greek Magical Papyri of the 2nd century BC to the 5th century AD describe scarabs as an ingredient in a spell. Their mouthparts are characteristic in lacking galeae and having a mobile tooth on their left mandible. Larvae tend to feed voraciously once they emerge from their eggs. In cooler temperate areas, life cycles may occupy much longer periods, even up to four years or more. [166] If normal food sources are scarce, they may feed on small caterpillars, young plant bugs, or honeydew and nectar. This beauty had been found trespassing in a friend's kitchen. In the cerambycid Onychocerus albitarsis, the antennae have venom injecting structures used in defense, which is unique among arthropods. Coleoptera, known as beetles, are a diverse taxonomic order that includes almost 400,000 species making it the largest order in the animal kingdom. Most beetles, however, do not cause economic damage and many, such as the lady beetles and dung beetles are beneficial by helping to control insect pests. Some click beetle larvae, called wireworms, feed on newly planted seeds and roots of plant crops (e.g., maize, cotton, potatoes); others feed in deadwood or on wood-boring beetle larvae (Cerambycidae). Scents may be spicy, fruity, or similar to decaying organic material. [76] Carbon dioxide is more soluble in water than either oxygen or nitrogen, so it readily diffuses out faster than in. The larvae and adults of some species of lady beetles (Coccinellidae) feed on aphids that are pests. The best-known of these are the Judean LMLK seals, where eight of 21 designs contained scarab beetles, which were used exclusively to stamp impressions on storage jars during the reign of Hezekiah. To endure the period without food (often lasting many months) adults prepare by accumulating reserves of lipids, glycogen, proteins and other substances needed for resistance to future hazardous changes of environmental conditions. They are pale, almost hairless, and fairly soft; they have either minute legs or none at all; and the eyes are poorly developed. Ecology, the relationship of organisms to each other and to their environment, represents fundamental interactions in nature. Beetles are prominent in human culture, from the sacred scarabs of ancient Egypt to beetlewing art and use as pets or fighting insects for entertainment and gambling. A fold (jugum) of the membrane at the base of each wing is characteristic. The bark beetle Pityogenes chalcographus can survive 39C whilst overwintering beneath tree bark;[131] the Alaskan beetle Cucujus clavipes puniceus is able to withstand 58C; its larvae may survive 100C. In Japan the Genji firefly, Luciola cruciata, is extremely popular, and in South Africa the Addo elephant dung beetle offers promise for broadening ecotourism beyond the big five tourist mammal species. This shedding, called "molting," may occur between seven to 10 times before the larvae enter the pupal . Click Beetles, Family Elateridae. Page and figure refer-ences are provided for 7 recent, comprehensive, and readily available pub-lications. [63] As the time for emergence of the adult approaches, the pupa may darken, especially the mandibles and eyes. He is black, long and has hard wings like a great dung beetle". Later it eats through the entire leaf. Likewise, predatory species of Cleroidea and Cucujoidea hunted their prey under the bark of trees together with the jewel beetles (Buprestidae). Other lady beetles feed on scale insects, whitefly and mealybugs. This beetle lives as a parasite both as a larva and as an adult, feeding on epidermal tissue and possibly on skin secretions and wound exudates. In such species, the male often has horns on the head or thorax, making its body length greater than that of a female. Several generations per year are possible with subtropical and tropical species. Many male beetles are territorial and fiercely defend their territories from intruding males. The hind legs of some beetles, such as flea beetles (within Chrysomelidae) and flea weevils (within Curculionidae), have enlarged femurs that help them leap. The pupal stage lasts four days or longer. Dermestids produce esters, and species of Elateridae produce fatty acid-derived aldehydes and acetates. Their bodies tend to be very solid and tough. The Chrysomeloidea diversified around the same time, feeding on a wide array of plant hosts from cycads and conifers to angiosperms. It is partly based on a manuscript by . The Curculionidae have elbowed or geniculate antennae. This loss of body fat was a gradual process, occurring in combination with dehydration. [133] The hemolymph of the mealworm beetle Tenebrio molitor contains several antifreeze proteins. [173] The Australian Dung Beetle Project (19651985), introduced species of dung beetle to Australia from South Africa and Europe to reduce populations of Musca vetustissima, following successful trials of this technique in Hawaii. With over 350,000 described species, beetles (order Coleoptera) represent the largest group of organisms on Earth. The disease has devastated elm trees across Europe and North America. [7] The function of the bubble is not only to contain a store of air but to act as a physical gill. Feather like flabellate antennae are a restricted form found in the Rhipiceridae and a few other families. The plants' ovaries are usually well protected from the biting mouthparts of their pollinators. Many beetles are aposematic, with bright colors and patterns warning of their toxicity, while others are harmless Batesian mimics of such insects. This can range from dung, which is consumed by coprophagous species (such as certain scarab beetles in the Scarabaeidae), to dead animals, which are eaten by necrophagous species (such as the carrion beetles, Silphidae). and more. The pterothorax is the fused meso- and metathorax, which are commonly separated in other insect species, although flexibly articulate from the prothorax. Order Coleoptera. In the Meloidae, the male climbs onto the dorsum of the female and strokes his antennae on her head, palps, and antennae. Coccinellid larvaeflattened, broad in the middle, and tapering at the backsometimes have a few low projections (tubercles) bearing short hairs and are often strikingly coloured with red or yellow and black. [6] Some, such as the boll weevil, which feeds on cotton buds and flowers, can cause extremely serious damage to agriculture. The larvae of many beetle families are predatory like the adults (ground beetles, ladybirds, rove beetles). The bombardier beetle's powerful repellent spray has inspired the development of a fine mist spray technology, claimed to have a low carbon impact compared to aerosol sprays. Different species use different pheromones. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Novel aspects of the biology of Chrysomelidae. Coleoptera are characterized by presenting great morphological variability, a characteristic that has allowed them to colonize all types of environments and habitats, from freshwater to marine environments. While most predatory beetles are generalists, a few species have more specific prey requirements or preferences. Long-horned beetle larvae (Cerambycidae) are parasitized by wasps that lay their eggs directly on or in beetle larvae. Several days ago, I received a fine image of a striking predator known as the big-headed ground beetle, Scarites subterraneus. Insecta: Coleoptera Staphylinidae adults and larvae, p. 1138-1174, In Dindal DL. They are wingless and eyeless, as are many other ectoparasites. Adults used to source H. ligniperda eggs originated from Kaingaroa Forest (Lat: 38 2447 S, Long: 176 2651 E . [7] The rove beetle Bledius spectabilis lives in salt marshes, so the eggs and larvae are endangered by the rising tide. [46] Beetles, both adults and larvae, are the prey of many animal predators including mammals from bats to rodents, birds, lizards, amphibians, fishes, dragonflies, robberflies, reduviid bugs, ants, other beetles, and spiders. The low temperatures experienced by Cucujus clavipes can be survived through their deliberate dehydration in conjunction with the antifreeze proteins. [2] They have a range of sizes and colours, but in terms of shape, they are usually narrow and parallel . The beetle families that habitually pollinate flowers are the Buprestidae, Cantharidae, Cerambycidae, Cleridae, Dermestidae, Lycidae, Melyridae, Mordellidae, Nitidulidae and Scarabaeidae. In many species, the larvae simply increase in size with each successive instar as more food is consumed. 1998; Yavorskaya et al. They bear thoracic legs but lack abdominal prolegs. ), Hydrophiloidea (2800, water scavenger beetles), Byrrhoidea (400, pill and turtle beetles, etc. This oxygen layer is known as a plastron and is . The abdomen is everything posterior to the thorax. [147] Images of the scarab in bone, ivory, stone, Egyptian faience, and precious metals are known from the Sixth Dynasty and up to the period of Roman rule. [96], Some dung beetles provide parental care, collecting herbivore dung and laying eggs within that food supply, an instance of mass provisioning. These include the pollen beetle Meligethes aeneus[142] and many species of coccinellids. Flowering events and beetle diversity in Venezuela. [6], Adults have extremely variable lifespans, from weeks to years, depending on the species. It covers all. They are suitable for this as their taxonomy is stable; their life history is well described; they are large and simple to observe when visiting a site; they occur around the world in many habitats, with species specialised to particular habitats; and their occurrence by species accurately indicates other species, both vertebrate and invertebrate. [184], Many beetles have durable elytra that has been used as material in art, with beetlewing the best example. The parents prepare the carcass and protect it from competitors and from early decomposition. Short review of the presocial evolution in Coleoptera. Weevil larvae, usually white and soft, are fatter in the abdominal region than at the head end. [175] Larvae feed on and remove cartilage along with other soft tissue. The defensive glands of carabid ground beetles produce a variety of hydrocarbons, aldehydes, phenols, quinones, esters, and acids released from an opening at the end of the abdomen. Spent mushroom substrate is made from the waste remaining after the harvest of mushrooms. Cerambycid larvae are long and slender, with swellings at the sides of the segments. Adults: Usually small, oval to oblong, highly convex (dome-shaped). [81], Competition can play a part in the mating rituals of species such as burying beetles (Nicrophorus), the insects fighting to determine which can mate. [71] Other soft wing beetles include the net-winged beetle Calopteron discrepans, which has brittle wings that rupture easily in order to release chemicals for defense. While most beetles use their legs for walking, legs have been variously adapted for other uses. . Coleoptera (beetles) are most probably the most versatile creatures on earth. The first discoveries from North America made in the Wellington Formation of Oklahoma were published in 2005 and 2008. [98], Subsociality, where females guard their offspring, is well-documented in two families of Chrysomelidae, Cassidinae and Chrysomelinae. Beetles are insects that form the order Coleoptera (/koliptr/), in the superorder Endopterygota. In Australia, the Koonwarra fossil beds of the Korumburra group, South Gippsland, Victoria, are noteworthy. Its penultimate larval stage is the pseudo-pupa or the coarcate larva, which will overwinter and pupate until the next spring. Genus Zilus Mulsant, 1850 Genus Zagloba Casey, 1899 [99][100][101][102][103], Eusociality involves cooperative brood care (including brood care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The typical form of metamorphosis in beetles passes through four main stages: the egg, the larva, the pupa, and the imago or adult. [115] Bombardier beetles have well-developed pygidial glands that empty from the sides of the intersegment membranes between the seventh and eighth abdominal segments. [24], Beetle fossils are abundant in the Cenozoic; by the Quaternary (up to 1.6 mya), fossil species are identical to living ones, while from the Late Miocene (5.7 mya) the fossils are still so close to modern forms that they are most likely the ancestors of living species. Most are in Europe and Asia and belong to the temperate climate zone during the Cretaceous. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. They split the Adephaga into 2 clades, Hydradephaga and Geadephaga, broke up the Cucujoidea into 3 clades, and placed the Lymexyloidea within the Tenebrionoidea. Kirmse S, Adis J, Morawetz W. 2003. C. punctulata is fast-moving, alert, and when approached can fly away several yards. [112][113] Beetles use a variety of anti-predator adaptations to defend themselves. Buprestidae) are present, but they remained rare until the Cretaceous. Scarabaeiform larvae are commonly called grubs. Larvae with relatively long thoracic legs and a . [7], Before mating, males and females may stridulate, or vibrate the objects they are on. As now constituted, Staphylinidae is the largest family of beetles, with over 63,000 species known worldwide and probably over 75% of tropical species still undescribed. This is known as hypermetamorphosis; it occurs in the Meloidae, Micromalthidae, and Ripiphoridae. [121] Most beetle-pollinated flowers are flattened or dish-shaped, with pollen easily accessible, although they may include traps to keep the beetle longer. [62][65][66], Beetles have mouthparts like those of grasshoppers. A bogarak (Coleoptera) az zeltlbak trzsnek s a rovarok osztlynak egyik rendje.Tudomnyos elnevezsk (Coleoptera) az grg eredet (jelentse: tok, burok) s (jelentse: szrny) szavakbl szrmazik. The Carabidae typically have thread-like antennae. [29][30][31] The first scarab beetles were not coprophagous but presumably fed on rotting wood with the help of fungus; they are an early example of a mutualistic relationship. Not exclusive; other regions may also be reported. The scarab was of prime significance in the funerary cult of ancient Egypt. Two pairs of finger-like appendages, the maxillary and labial palpi, are found around the mouth in most beetles, serving to move food into the mouth. Not to be confused with. Definition: This organism is known to be present in this location or region. For the English rock band, see, "Coleoptera" redirects here. [5], Beetles are by far the largest order of insects: the roughly 400,000 species make up about 40% of all insect species so far described, and about 25% of all animal species. By the mid-1920s, it had entered all cotton-growing regions in the US, traveling 40to 160 miles (60260km) per year. New record and remeasuring of Scydosella musawasensis Hall, 1999 (Coleoptera, Ptiliidae), the smallest known free-living insect", "Evolution of the elytral venation and structural adaptations in the oldest Palaeozoic beetles (Insecta: Coleoptera: Tshekardocoleidae)", Journal of the Kansas Entomological Society, "Early evolution of beetles regulated by the end-Permian deforestation", "A new genus and two new species of fossil elaterids from the Yixian Formation of Western Liaoning, China (Coleoptera: Elateridae)", "Jurassic and Lower Cretaceous Buprestidae (Coleoptera) from Eurasia", "Fossil insects from the Tithonian 'Solnhofener Plattenkalke' in the Museum of Natural History, Vienna", "A new genus of elateriform beetles (Coleoptera, Polyphaga) from the Middle-Late Jurassic of Karatau", "New ommatids from the Late Jurassic of western Liaoning, China (Coleoptera: Archostemata)", "New beetles of the family Cupedidae from the Mesozoic of Mongolia. The Attelabidae roll leaves and lay their eggs inside the roll for protection. [172] The American Institute of Biological Sciences reports that dung beetles save the United States cattle industry an estimated US$380million annually through burying above-ground livestock feces. In most pupae, the appendages are not attached to the body and are said to be exarate; in a few beetles (Staphylinidae, Ptiliidae etc.) Short (decreasing) day length serves as a signal of approaching winter and induces winter diapause (hibernation). At present, more species of beetles are known than of any other insect order. Materials and Methods. [105] This Australian species lives in horizontal networks of tunnels, in the heartwood of Eucalyptus trees. Young larvae did not survive on any substrate except the spent L. edodes substrate (36.7%). (2015) used eight nuclear genes for 367 species from 172 of 183 Coleopteran families. [86], The larval period can vary widely. Beetle larvae can often be confused with those of other endopterygote groups. The mountain pine beetle emits a pheromone to attract other beetles to a tree. About 75% of all insect species go through the four stages of complete metamorphosis - egg, larva, pupa, and adult. [58], The head, having mouthparts projecting forward or sometimes downturned, is usually heavily sclerotized and is sometimes very large. This has made them the group of animals with the greatest evolutionary success. The mites of the family Tetranychidae (Acari: Prostigmata), known as spider mites, are severe pests of economic crops, fruits and . There are several types of coleopteran larvae. After the tree's defenses have been exhausted, the beetles emit an anti-aggregation pheromone. In some cases the pupa lies on a cushion of frass (chewed or torn wood fibres) or other material; in others it is enclosed in a cocoon of frass or other material (e.g., a smooth, white, hard covering similar to the shell of a birds egg). the appendages are fused with the body (termed as obtect pupae). The mandibles appear as large pincers on the front of some beetles. [125] Chemically mediated by a bacterially produced polyunsaturated peroxide,[126] this mutualistic relationship between the beetle and the fungus is coevolved. The mouthparts are rarely suctorial, though they are sometimes reduced; the maxillae always bear palps. [91], Beetles have a variety of ways to communicate, including the use of pheromones. Over one-quarter of all known species of animals are beetles. [148] The scarab was linked to Khepri, the god of the rising sun, from the supposed resemblance of the rolling of the dung ball by the beetle to the rolling of the sun by the god. It is one of more than 300 species of wood-boring Ambrosia beetles which distribute the spores of ambrosia fungi. This is the largest order in the class Insecta with over 250,000 described species. Coleoptera are holometabolus, thus possess distinct egg, larval, pupal, and adult stages. [109], Decaying organic matter is a primary diet for many species. Some species are highly threatened while others are already feared extinct. [174], The Dermestidae are often used in taxidermy and in the preparation of scientific specimens, to clean soft tissue from bones. The family of Chironomidae is a group of Diptera insects belonging to the suborder of Nematocera, commonly called "non-biting midges" in the adult stage and "bloodworms" in the larval stage. [6], Beetle larvae can be differentiated from other insect larvae by their hardened, often darkened heads, the presence of chewing mouthparts, and spiracles along the sides of their bodies. [67], The multisegmented legs end in two to five small segments called tarsi. Many are familiar to us like ladybugs, Japanese beetles, fireflies and dung beetles. [114], Other species have special glands to produce deterrent chemicals. Media in category "Coleoptera larvae" The following 69 files are in this category, out of 69 total. This volume will be invaluable to all who need to identify carabid larvae from Northern Europe, and provides the only complete and detailed text, including specific descriptions, of the larvae of this important group of beetles. The beetle faces the early morning breeze, holding up its abdomen; droplets condense on the elytra and run along ridges towards their mouthparts. A birch bookcase 40 years old released adult Eburia quadrigeminata (Cerambycidae), while Buprestis aurulenta and other Buprestidae have been documented as emerging as much as 51 years after manufacture of wooden items. [7] To attract a mate, fireflies (Lampyridae) use modified fat body cells with transparent surfaces backed with reflective uric acid crystals to produce light by bioluminescence. After the body of the adult has hardened, the adult breaks or dissolves the barrier and emerges. The pupa usually rests with its camouflage flat over its back, although it may erect the camouflage and turn it back to discourage an enemy. Such a bubble may be contained under the elytra or against the body by specialized hydrophobic hairs. [6], Essentially all beetles lay eggs, though some myrmecophilous Aleocharinae and some Chrysomelinae which live in mountains or the subarctic are ovoviviparous, laying eggs which hatch almost immediately. . It remains the most destructive cotton pest in North America. Some aquatic beetle species may use antennae for gathering air and passing it under the body whilst submerged. These include members of the Histeridae and Silphidae, preying on the larvae of coprophagous and necrophagous insects. insects that undergo the process of metamorphosis - they are known as holometabolous insects. During each molt the old larval skin is pushed back and attached to processes at the hind end. Some beetles undergo hypermetamorphosis, in which they have different larval types in different instars (the stages between molts). The big-headed ground beetle is part of a very large family of beetles called ground beetles, a clan more than 40,000 species strong. In Eupompha, the male draws his antennae along his longitudinal vertex. M. Voracity and feeding preferences of larvae and adult stages of Stethorus gilvifrons Mulsant (Coleoptera: Coccinellidae) on larvae and adult of Oligonychus afrasiaticus McGregor (Acarina: Tetranychidae . This further segmentation is usually best seen on the abdomen. [64] Antennae vary greatly in form, sometimes between the sexes, but are often similar within any given family. The unfolding and folding of the wings is operated by muscles attached to the wing base; as long as the tension on the radial and cubital veins remains, the wings remain straight. Beetle families may use antennae in different ways. The name of the taxonomic order, Coleoptera, comes from the Greek koleopteros (), given to the group by Aristotle for their elytra, hardened shield-like forewings, from koleos, sheath, and pteron, wing. Dermestid larvae, somewhat tapering and cylindrical, have whorls of short bristles and some longer ones and resemble hedgehogs or porcupines. frontalis: beetle larvae seldom survived in the presence of O. minus (compared to 83% survival elsewhere). For example, the tansy beetle walks between habitats despite being physically capable of flight. Titan beetle, Titanus giganteus, a tropical longhorn, is one of the largest and heaviest insects in the world. A bogarak rendjnek valban egyik legfeltnbb sajtossga, hogy . [49], The consistency of beetle morphology, in particular their possession of elytra, has long suggested that Coleoptera is monophyletic, though there have been doubts about the arrangement of the suborders, namely the Adephaga, Archostemata, Myxophaga and Polyphaga within that clade. [28] Around the same time, numerous primitive weevils (e.g. 12.2.3 Myxophaga. Dorsal surface smooth, pubescent (having short, fine hairs), or both. There are more known . [119] A few groups of beetles are primary parasitoids of other insects, feeding off of, and eventually killing their hosts. A. Elmidae (Coleoptera, Byrrhoidea) larvae in the state of So Paulo . For example, when moving quickly, tiger beetles may not be able to see very well and instead hold their antennae rigidly in front of them in order to avoid obstacles. Beetles are probably attacked by fewer predators than many other insects; birds that often feed on various kinds of insects may not eat some kinds of beetles. [151], Pliny the Elder discusses beetles in his Natural History,[152] describing the stag beetle: "Some insects, for the preservation of their wings, are covered with an erust (elytra)the beetle, for instance, the wing of which is peculiarly fine and frail. Digestion takes place mostly in the anterior midgut, although in predatory groups like the Carabidae, most digestion occurs in the crop by means of midgut enzymes. 4:716. Like other tiger beetles its head is larger than the thorax. [70] Some beetles have lost the ability to fly. [72], Beetles' flight wings are crossed with veins and are folded after landing, often along these veins, and stored below the elytra. [23] However, there are only a few fossils from North America before the middle Permian, although both Asia and North America had been united to Euramerica. The general anatomy of a beetle is quite uniform, although specific organs and appendages vary greatly in appearance and function between the many families in the order. [128] A study of hibernation in the Arctic beetle Pterostichus brevicornis showed that the body fat levels of adults were highest in autumn with the alimentary canal filled with food, but empty by the end of January. [202][203], Since beetles form such a large part of the world's biodiversity, their conservation is important, and equally, loss of habitat and biodiversity is essentially certain to impact on beetles. Popular dislike of pest beetles, too, can be turned into public interest in insects, as can unusual ecological adaptations of species like the fairy shrimp hunting beetle, Cicinis bruchi.[207]. Dates of origin of major groups are shown in italics in millions of years ago (mya). [134] The Alaskan beetle Upis ceramboides can survive 60C: its cryoprotectants are xylomannan, a molecule consisting of a sugar bound to a fatty acid,[135] and the sugar-alcohol, threitol. [205] Conservationists have attempted to arouse a liking for beetles with flagship species like the stag beetle, Lucanus cervus,[206] and tiger beetles (Cicindelidae). In general, wood-boring beetles and root feeders have the longest life cycles, while leaf-feeding species have shorter ones. [47] Myxophaga contains about 65 described species in four families, mostly very small, including Hydroscaphidae and the genus Sphaerius. Dytiscidae (diving beetles), Geadephaga (35000) e.g. Examples of internal feeders are most Buprestidae and longhorn beetles. As in other insects, a segmented tube-like heart is attached to the dorsal wall of the hemocoel. [77], Like other insects, beetles have open circulatory systems, based on hemolymph rather than blood. [24] Larvae are very variable, all with distinct sclerotised head, strongly developed mandibles, 2-3 segmented antenna; 3 pairs of jointed thoracic legs, lacking abdominal prolegs; open peripneustic (9 pairs of spiracles) tracheal system, but variably reduced spiracle number in most aquatic larvae, some with lateral and/or ventral abdominal gills, [116] The click beetles (Elateridae) can suddenly catapult themselves out of danger by releasing the energy stored by a click mechanism, which consists of a stout spine on the prosternum and a matching groove in the mesosternum.
