Byrrhoidea

Dryopidae is a family of beetles, commonly named long-toed water beetles, in the superfamily Byrrhoidea. It was described by Gustaf Johan Billberg in 1820.

Byrrhoidea is a superfamily of beetles belonging to Elateriformia that includes several families which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, most of the remaining Polyphagan beetles which are aquatic are in this superfamily.

Heteroceridae, the variegated mud-loving beetles, are a widespread and relatively common family of beetles found on every continent except for Antarctica.

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. The oldest fossils of the family are known from mid-Cretaceous Burmese

Eulichadidae is a family of beetles belonging to Elateriformia. There are two extant genera, Eulichas with several dozen species native to the Indomalayan realm of Asia, and Stenocolus, with a single species native to Western North America. The larvae are aquatic, with the larvae of Eulichas being found in sandy sediments of clean forest streams, while the larvae of Stenocolus are found under rocks and in leaf packs in low elevation streams and rivers. They are herbivorous or saprophagous with larval specimens of Eulichas having been found with wood particles in their stomachs, while the larva

Callirhipidae (also known as Callirhipidae Cedar Beetles) is a family of beetles, found widely throughout low-latitude regions except tropical Africa and Madagascar. There are around 175 species in 7 genera. The larvae bore into dead wood and generally have a life span of 2 or more years. The adults are generally nocturnal.

Chelonariidae or turtle beetles is a family of beetles in the superfamily Byrrhoidea. It was described by Blanchard in 1845. There are 3 genera with around 300 described species. Little is known of their ecology, though it seems they are associated with the roots of orchids and the nests of ants and termites. Their exoskeletons are heavily sclerotised and their limbs can be effectively retracted into their bodies due to the presence of socket-like cavities. Adult specimens have seed-shaped bodies that are typically colored brown or black with lighter patches.

Lutrochidae is a family of water beetles with a single genus Lutrochus sometimes known as "Travertine beetles". There are around 21 species native to the Americas from the southern United States to Brazil.

Ptilodactyla is a genus of toe-winged beetles in the family Ptilodactylidae. Around 380 species are described in Ptilodactyla, about 70% of all species in the family. However, it may be subject to divisions in the future, and there are likely many more undescribed species. thumb thumb
