Chrysolina is a large genus of leaf beetles in the subfamily Chrysomelinae. Most species are distributed in Europe, Asia and Africa with a small number of species inhabiting North America and introduced species in Australia.
Donacia is a large genus of aquatic leaf beetles in the subfamily Donaciinae. Like other members of that subfamily, the beetles have long antennae. They are active and able to fly. Larvae feed on submerged portions of aquatic plants, such as water lilies, and breathe oxygen from plant vessels. Adults live on surface parts of the same plants.
Stenus is a genus of semiaquatic rove beetles in the subfamily Steninae, and one of the largest genera in the kingdom Animalia, with some 3100 known species worldwide. They are predators of Collembola and other small arthropods. Adults have a protrusible labium with a sticky tip used in prey capture. To overcome the rapid escape of Collembola, the labium is protruded at high speed by hemolymph pressure, and immediately withdrawn, pulling the prey within the range of the mandibles. However, the labium tip does not easily stick to prey covered in scales or setae or that have a large body size. Stenus comma is more likely to catch such prey by lunging forward and grabbing them directly with its mandibles rather than using its labium. Stenus species are also known for "skimming" on the water surface using their pygidial gland secretions that act as a surfactant and rapidly propel the beetle fast forward, a phenomenon known as the Marangoni effect. Stenus comma has been seen to achieve a velocity of 0.75 m/s, and to cover a distance of up to 15 m if the secretion is continuous.
Rhizophagus is a genus of beetles in the family Monotomidae.
Cercyon is a genus of water scavenger beetles in the family Hydrophilidae. There are at least 50 described species in Cercyon.
