Dytiscus
''Dytiscus'' ("little diver" based on Greek language, Greek ''δυτικός'', "able to dive" and the diminutive suffix ''-ίσκος'') is a Holarctic genus of predaceous diving beetles that usually live in wetlands and ponds. There are 26 species in this genus distributed in Europe, Asia, North Africa and North and Central America. They are predators that can reduce mosquito larvae. ''Dytiscus'' are large water beetles with a robust, rounded shape and they measure long depending on the exact species involved. The largest, ''Dytiscus latissimus, D. latissimus'', is among the largest species in the family and its size is only matched by certain ''Megadytes''. The tarsi of the males are modified into suckers which are used to grip the female in mating. Females are usually larger than the males and come in two forms, with grooved (sulcate) or smooth elytra. Males only ever have smooth elytra. The adults of most species can fly. Life history Adult beetles and their larvae are aqu ...

Dytiscus Latissimus
''Dytiscus latissimus'' is a large species of aquatic beetle in family Dytiscidae. It is native to Europe and considered threatened. Description One of the largest representatives of the predaceous diving beetles of the family Dytiscidae (its maximum size only exceeded by the Brazilian '' Megadytes ducalis''), ''D. latissimus'' can reach a length around . This beetle is similar in structure to the better-known and widespread '' D. marginalis'', but it is clearly larger and especially wider. The species is usually easy to recognize by the extensions on both sides of the shield. The elytra and the pronotum are dark brown with yellow sides. The head is black, while the legs are yellow. The male's wing cases are shiny, while those of the female are finely grooved. This voracious predator hunts a wide variety of prey, including other insects, tadpoles, and small fish. Before they dive, they collect air bubbles in their wing cases which go through the spiracles. Distribution This spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predaceous Diving Beetle
The Dytiscidae, from the Ancient Greek word δυτικός (''dystikos''), meaning "able to dive", are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live in terrestrial habitats such as among leaf litter. The “diving” in their common name comes from their cycling between underwater and the surface to replenish oxygen like a diver. The adults of most are between long, though much variation is seen between species. The European ''Dytiscus latissimus'' and Brazilian '' Bifurcitus ducalis'' are the largest, reaching up to respectively, although the latter is listed as extinct by the IUCN. In contrast, the smallest is likely the Australian '' Limbodessus atypicali'' of subterranean waters, which only is about long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appetit ...
