The bank humid beetles (Noteridae) are a family of beetles .

features

The beetles are one to 6.3 millimeters long and have an oval, streamlined, usually brown, black or translucent body that looks very similar to that of swimming beetles. They differ from this family, however, in the hips of the rear pairs of legs , which are plate-shaped towards the rear and thus cover the attachment of the rear thigh ring. Some species look similar to water beetles , but they differ from these by their thread-like antennae , which have eleven links. All legs have five tarsal links. The tarsi of the hind legs are not covered with webbed hairs in all species. The head of the animals is short and the pronotum slightly covered.

Way of life

Both the larvae and the adults live underwater. The beetles can swim well and move around by rowing their hind legs at the same time. The animals live in stagnant water or flowing water with slow currents. They are usually found between the roots of plants floating on the surface of the water, but also in the bank mud and substrate at the bottom of the water. Larvae and beetles feed predatory and on dead animals, but they also eat parts of plants.

Systematics (Europe)

The bank humid beetles occur worldwide with about 270 species, in Europe they are represented with only four species, of which two species also live in Central Europe ( Noterus clavicornis , Noterus crassicornis ). The family used to be considered a subfamily of the swimming beetles (Dytiscidae), to which they are very closely related. Their main distribution area are the tropics .
