Species of this family are found in dried leaves and in leaf litter. They have been known to occur in large numbers indoors and sometimes swarm at dusk, drifting on the wind in the manner of aphids. They are sometimes attracted to newly painted surfaces and can be a nuisance in new houses.


Venation is of the Caecilius type. The wings are glabrous and the tarsi are 2-segmented; terminal structures of the male abdomen are complex but the phallosome is simple; female gonapophyses are reduced.
