Dytiscidae
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 appe ...

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] |

Bifurcitus Ducalis
''Bifurcitus ducalis'', formerly ''Megadytes ducalis'', is a species of water beetle in the family Dytiscidae. It is the largest species in the family. Until recently, the species was only known from a single specimen that was collected in the 19th century from Brazil, but more specimens, also collected in the 19th century from Brazil, were discovered in 2019. Although listed as extinct by the IUCN, the limited studies conducted on water beetles in Brazil means that it might still survive. History The first specimen of ''B. ducalis'' was collected in the 19th century from an unknown locality in Brazil and is kept at the Natural History Museum, London. Rumors indicated it was found in the bottom of a canoe in the Amazon. In 2019, a study reported 10 additional specimens (including the first female of the species), all collected in the late 19th century, discovered incidentally in the National Museum of Natural History of France.
