Dytiscidae
The Dytiscidae – based on the Greek ''dytikos'' (δυτικός), "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 among leaf litter. The adults of most are between long, though much variation is seen between species. The European ''Dytiscus latissimus'' and Brazilian ''Megadytes ducalis'' are the largest, reaching up to and respectively. 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 appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megadytes Ducalis
''Megadytes ducalis'' is a species of water beetle in the family Dytiscidae. With a length of , it is the largest species in the family. Until recently, the species was only known from a single specimen that was collected in the 1800s from Brazil, but more specimens were discovered in 2019. History The first specimen of ''M. ducalis'' was collected in the 1800s from an unknown locality in Brazil. Rumors indicate 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 from the end of the 19th century, discovered incidentally in various historical collections. While the original holotype lacked any location data, the new specimens all indicate that they were collected in Santo Antonio da Barra (now known as Condeuba) in the southern part of Bahia, Brazil. Villagers in the region were involved in insect trade, capturing the much sought after specimens of '' Hypocephalus armatus' ...

Dytiscus Latissimus
''Dytiscus latissimus'' is a species of beetle in family Dytiscidae. Description One of the largest representatives of the predaceous diving beetles of the genus '' Dytiscus'', ''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 species can be found in northern and central European countries. The species is listed on Annex II and Annex IV of the European Union Habita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dytiscus Marginalis Larva
''Dytiscus'' ("little diver" based on 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, '' 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 aquatic but the pupae spend their lif ...
