The threadlike (Nemopteridae) are an animal family in the order of the reticulated winged (Neuroptera). They occur worldwide with about 150 kinds in two subfamilies; in Europe only seven species are native, none of which in Central Europe occurs. Their distribution is limited to deserts and other dry areas on earth.
features
The threadlike reach a forewing length of 7 to 35 millimeters, the hind wings are 19 to 90 millimeters long. The latter are drawn out in a very narrow thread-like manner, which is where the animals get their German name from. At the end, these threads are widened spoon-shaped in some species. The forewings are in some species, such as. B. in the genus Nemoptera , stained. Her head is trunk-shaped and narrow, the compound eyes protrude laterally.
The larvae look similar to the ant lions , but the prothorax of the subfamily Crocinae is very elongated.
Way of life
There are day, night and twilight active species that sometimes occur in large numbers. The adults feed on pollen. The larvae of the subfamily Nemopterinae live in the sand or litter and hunt for ant larvae . The larvae of the Crocinae live in the dust in small caves and in other dark places and mainly eat dust lice and other insects. The threadlike development takes one to three years.
