Also known as “spoonwings” and “ribbon-winged lacewings,” thread-winged antlions are characterized by a slender body, net-veined forewings, and very long hindwings. In some species, the hindwings have conspicuous, feather-like tips.
Adults are slow fliers and mainly active in late spring. Males attract females by dispersing chemical pheromones. Females lay eggs in the sand.
Adults feed on nectar and pollen. Larvae feed on insects.
Open grasslands with sandy soil, including the Pella region.
