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 1 and 2.5 cm (0.4–1.0 in) long, though much variation is seen between species. The European Dytiscus latissimus and Brazilian Megadytes ducalis are the largest, reaching up to 4.5 cm (1.8 in) and 4.75 cm (1.9 in) respectively. In contrast, the smallest is likely the Australian Limbodessus atypicali of subterranean waters, which only is about 0.9 mm (0.035 in) 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.
The Perkin Medal is an award given annually by the Society of Chemical Industry to a scientist residing in America for an "innovation in applied chemistry resulting in outstanding commercial development." It is considered the highest honor given in the US chemical industry.
Hydraenidae is a family of very small aquatic beetles, sometimes called "minute moss beetles", with a worldwide distribution. These beetles are generally 1–3 mm in length with clubbed antennae. They do not swim well and are generally found crawling in marginal vegetation. Most are phytophagous but a few saprophagous and predatory species are known.
Rhantus is a genus of beetle in family Dytiscidae. There are about 100 species distributed worldwide. They often live in pools and marshy habitat types. Several species have colonized oceanic islands and become endemics.
Hydrochus is a genus of water scavenger beetles in the monogeneric family Hydrochidae, sometimes placed in the Hydrophilidae as a subfamily Hydrochinae. The family Hydrochidae includes about 180 species, all of which are placed in the genus Hydrochus. Hydrochus has also been used for a fly genus in the family Dolichopodidae. This junior homonym is a junior subjective synonym of the genus Rhaphium.
Hydroporus is a genus of water beetles native to the Palearctic, the Nearctic, the Near East, and North Africa. It contains the following species:
Hygrobia is a genus of aquatic beetles native to Europe, North Africa, China and Australia. It is the only genus in the family Hygrobiidae, also known as the Paelobiidae. These are known commonly as squeak beetles or screech-beetles.
Enochrus, a genus of water scavenger beetles, is the third-largest genus of hydrophilids with 222 species in six subgenera worldwide.
Helochares is a genus of water scavenger beetles in the family Hydrophilidae, represented by 161 described species. It is distributed across the Afrotropical, Australasian, Indo-Malayan, Nearctic, and Palearctic realms.
Anacaena is a genus of water scavenger beetles in the subfamily Hydrophilinae. It is an extant genus but there is at least one fossil species.
Olibrus is a genus of shining flower beetles in the family Phalacridae. There are at least 30 described species in Olibrus.
Laccobius is a genus of water scavenger beetles in the family Hydrophilidae. There are more than 80 described species in Laccobius.
Dactylosternum is a genus of water scavenger beetles in the family Hydrophilidae. There are more than 20 described species in Dactylosternum.
Gymnochthebius is a genus of minute moss beetles in the family Hydraenidae. There are more than 60 described species in Gymnochthebius.
Coelostoma is a genus of beetles belonging to the family Hydrophilidae. The genus was first described by Brullé in 1835. The genus has cosmopolitan distribution, with 111 described species, representing one of the most diverse genera of Hydrophilidae.
Agraphydrus is a genus of water scavenger beetle in the family Hydrophilidae represented by 205 described species. It is distributed across the Afrotropical, Australasian, and Indomalayan realms.
