Eucnemidae, or false click beetles, are a family of elateroid beetles based on the type genus Eucnemis ; they include about 1700 species, distributed worldwide.
Closely related to the family Elateridae, specimens of Eucnemidae can reach a length of 2–30 mm (0.079–1.181 in). Bodies are slightly flattened and convex. The upper surfaces of the body usually has hairs, setae or scales.
The larvae are typically legless, and generally develop feeding on the fluids of rotting wood, likely vomiting digestive enzymes into the wood to break apart the fungal hyphae, moving using their shovel shaped heads to force apart the wood. Adults, which are typically found on broken surfaces of trunks and stumps, have a short lifespan and it is unclear whether they feed, though they are capable fliers, and like some other elateroids are capable of clicking.

Tiger beetles are a family of beetles, Cicindelidae, known for their aggressive predatory habits and running speed. The fastest known species of tiger beetle, Rivacindela hudsoni, can run at a speed of 9 km/h, or about 125 body lengths per second. As of 2005, about 2,600 species and subspecies were known, with the richest diversity in the Oriental (Indo-Malayan) region, followed by the Neotropics. While historically treated as a subfamily of ground beetles (Carabidae) under the name Cicindelinae, several studies since 2020 indicated that they should be treated as a family, the Cicindelidae, which are a sister group to Carabidae within the Adephaga.
The whirligig beetles are water beetles, comprising the family Gyrinidae that usually swim on the surface of the water if undisturbed, though they swim underwater when threatened. They get their common name from their habit of swimming rapidly in circles when alarmed, and are also notable for their divided eyes which are believed to enable them to see both above and below water. The family includes some 700 extant species worldwide, in 15 genera, plus a few fossil species. Most species are very similar in general appearance, though they vary in size from perhaps 3 mm to 18 mm in length. They tend to be flattened and rounded in cross section, in plain view as seen from above, and in longitudinal section. In fact their shape is a good first approximation to an ellipsoid, with legs and other appendages fitting closely into a streamlined surface. Whirligig beetles belong to the beetle suborder Adephaga, which also includes ground beetles and diving beetles.
The Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives. It consists of about 25,000 species.
Buprestinae is a subfamily of beetles in the family Buprestidae, containing the following genera in the tribes Anthaxiini, Buprestini, Chrysobothrini, Melanophilini, and Xenorhipidini:
Chrysochroinae is a subfamily of beetles in the family Buprestidae: the "jewel beetles".
Physodeutera is a genus of Tiger Beetles endemic to Madagascar. There are more than 60 described species in Physodeutera.
Pogonostoma is a genus of Tiger Beetles endemic to Madagascar.
The Aleocharinae are one of the largest subfamilies of rove beetles, containing over 12,000 species. Previously subject to large-scale debate whether the subfamily deserved the familial status, it is now considered one of the largest subfamilies of rove beetles.
Agrilini is a tribe of metallic wood-boring beetles in the family Buprestidae. There are at least 40 described genera in Agrilini.
Ptilodactylidae is a family of beetles belonging to the Elateriformia. There around 500 extant species in 35 genera. They are generally associated with riparian and aquatic habitats. The larvae generally live associated with rotting wood or vegetation, or within gravel and detritus on the edge of water bodies. The larvae of some species feed on submerged rotting wood or on plant roots, while the adults of some species are known to feed on fungus with modified brush-like maxillae.
Throscidae is a family of elateroid beetles found worldwide with around 150 species in 5 extant genera. The larvae are soil-dwelling, siphoning fluid from mycorrhizae attached to trees. The adults are short-lived, with the adult males being noted for a complex mating dance. Like some other elateroids, they are capable of clicking.
Melasinae is a subfamily of false click beetles in the family Eucnemidae.
Agrypninae is a subfamily of click beetles in the family Elateridae. There are at least 130 genera and more than 430 described species in Agrypninae.
Trixagus is a genus of small false click beetles in the family Throscidae. There are more than 30 described species in Trixagus.
Balgus is a genus of click beetle. They are one of several genera in the family which contain at least one bioluminescent species. The genus was originally placed in the family Eucnemidae, later transferred to Throscidae, but recent classifications establish them firmly within Elateridae.
Melasis is the type genus of false click beetles of subfamily Melasinae and tribe Melasini. It contains fourteen species, native to North America and parts of Europe, four of which can be found in the Nearctic realm.
Tribalus is a genus of beetles belonging to the family Histeridae. There are seven species occurring in the western Palaearctic. Apart from that, most species are distributed throughout Oriental and African regions.
The Eucneminae are a subfamily of "false click beetle" genera, erected by Johann von Eschscholtz in 1889.
Mesogenus is a genus of mostly Asian click beetle allies in the subfamily Eucneminae and typical of the tribe Mesogenini, erected by Viscount Henri de Bonvouloir in 1871.
