The brook-like (Osmylidae) are a family of the reticulated winged (Neuroptera), which is distributed worldwide with the exception of North America . It comprises about 160 species , in Europe only one genus with three species is native. They are probably closely related to the lacewing (Chrysopidae).
features
Bach-like reach a fore wing length of 15 to 30 millimeters. They have large wings , the veins of which form a network-like structure. The wings of the European species are spotted. The thread-like antennae of the animals are relatively short. In addition to the compound eyes , the animals also have three point eyes (Ocelli). Just like the lacewing, the Bach-like glands also have on the prothorax with which they can emit a foul smelling odor.
The larvae have a long and narrow body and, as mouth parts, long, thread-like suction tubes that are slightly bent outwards. At the end of the abdomen they have two fold-out extensions with hooks on them. With these, they can both move around and grab prey.
Way of life
The adults are active during the day or at dusk. They can only fly badly and live mainly predatory, but also eat pollen . Some of the females lay their eggs near bodies of water. The larvae of the European species live predatory in the bank area of water and live partly in the water, partly on land.
