The dwarf wasps (Mymaridae), also called egg parasitic wasps , are a family of the wasps (Chalcidoidea).

description

All representatives of the dwarf wasps have narrow, more or less stalked wings, which are long and delicately ciliate at the edges. The end link of the feeler is usually enlarged and thus also a distinguishing feature. The dwarf wasps are mostly black, but there are also yellow in their coloration. The smallest insects are the males of the species Dicopomorpha echmepterygis with a length of only 0.139 millimeters.

With their paddle-shaped reduced fore wings, they are not good fliers, but are mainly spread by the wind. Some aquatic genera are known. Some “fly” under water because the difference between air and water is minimal for small body sizes, others use their legs to move.

Pygmy wasps lay their eggs in the eggs of other insects (especially Hemiptera ), which they feed on as they develop. They therefore play an important role in biological pest control.

More than 1400 species in approx. 100 genera are known worldwide, including:
