Tiger beetles are a large group of beetles, from the Cicindelinae subfamily, 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. The group has been suggested to represent a distinct family, the Cicindelidae, as the sister group to Carabidae.
Scydmaeninae are a subfamily of small beetles, commonly called ant-like stone beetles or scydmaenines. These beetles occur worldwide, and the subfamily includes some 4,500 species in about 80 genera. Established as a family, they were reduced in status to a subfamily of Staphylinidae in 2009
The Lycidae are a family in the beetle order Coleoptera, members of which are commonly called net-winged beetles. These beetles are cosmopolitan, being found in Nearctic, Palearctic, Neotropical, Afrotropical, Oriental, and Australian ecoregions.
Melyridae are a family of beetles of the superfamily Cleroidea.
Prionoceridae is a small family of beetles, in the suborder Polyphaga. They form a group within the cleroid beetles and were formerly treated as a subfamily (Prionocerinae) within the family Melyridae. Very little is known of their life history but most species are pollen feeders as adults and occur in large numbers during spring or the host flowering season. Larvae are predatory or feed on decomposing wood.
Cneoglossidae is a family of beetles in the superfamily Byrrhoidea, containing nine described species in a single genus, Cneoglossa, which are native to the Neotropics from Mexico to Brazil. The larvae develop inside rotting submerged branches found in small fast flowing shallow streams.
Scirtidae is a family of beetles (Coleoptera). These beetles are commonly referred to as marsh beetles, as the larvae are typically associated with stagnant water, but can be found in flowing water. Adults prefer decomposing plant material near the water's edge. More than an estimated 600 species are known worldwide, distributed among at least 60 genera.
Bactridium is a genus of root-eating beetles in the family Monotomidae. There are about 18 described species in Bactridium.
Cantharinae is a subfamily of beetles in the family Cantharidae. There are at least 200 described species in Cantharinae.
Chalepini is a tribe of leaf beetles in the family Chrysomelidae. There are at least 50 genera and 830 described species in Chalepini.
Cicindelini is a tribe of tiger beetles in the family Carabidae, containing the overwhelming majority of genera (>110) and species in the subfamily.
Limnichidae, commonly called minute marsh-loving beetles, is a family of beetles belonging to Byrrhoidea. There are at least 30 genera and 350 described species in Limnichidae. They are found worldwide, with the greatest diversity in tropical regions. Most species seem to be associated with water-adjacent habitats, such as riparian and coastal locations, though many species are likely fully terrestrial, with some species being associated with leaf litter and arboreal habitats. Species with known diets feed on moss or algae.
Dascillidae is a family of beetles within the clade Elateriformia. There are about 100 extant species in 11 genera, which are found worldwide. Dascillidae together with Rhipiceridae form the super family Dascilloidea.
Artematopodidae is a family of soft-bodied plant beetles in the superfamily Elateroidea. They are mostly found in understory forest foliage. The life history of the group is obscure, larvae of the genera Eurypogon and Macropogon likely feed on moss, while the larvae of Artematopus have been fed insect remains.The oldest fossils of the family date to the Middle Jurassic.
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.
Lycinae is a subfamily of net-winged beetles in the family Lycidae.
Malachiini is a large tribe of soft-winged flower beetles in the family Melyridae.
Ptilodactyla is a genus of toe-winged beetles in the family Ptilodactylidae. There are more than 30 described species in Ptilodactyla.
Scirtes is a genus of marsh beetles in the family Scirtidae. There are more than 80 described species in Scirtes.
