	Eulichadidae 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 herbivious/saprophagous with larval specimens of ''Eulichas'' having been found with wood particles in their stomachs, while the larvae of ''Stenocolus'' are known to feed on decaying roots and detritus. The adults are terrestrial, with specimens of ''Eulichas'' typically found using light, while specimens of ''Stenocolus'' are typically found in riparian vegetation, and are not attracted to light. Potential extinct genera have been described from Mesozoic rocks, but the placement of several of these taxa in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Byrrhoidea 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. Description Adults of many Byrrhoidea have exocone eyes (with expanded corneal lens). The anterior edge of the scutellar shield is often abruptly elevated (except in Psephenidae and Cneoglossidae). A variety of byrrhoids have the first three abdominal ventrites solidly fused together. Larvae of most Limnichiidae have one pair of anal hooks on the tenth abdominal segment, while Cneoglossidae and Ptilodactylidae have three or more hooks on each side of this segment. Larvae of Lutrochidae and Elmidae, as well as the limnichiid genus ''Hyphalus'', have anal gill tufts. Almost all byrrhoid larvae have anterior abdominal spiracles that are biforous (or bilabiate) in shape. The degree of wing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
