PTILIIDAE

Ptiliidae is the featherwing beetles family of insects of the order Coleoptera. The family contains the smallest known beetles, some measuring 0.5 mm in length. The members of the family all have wings made up of a narrow central strap fringed with long hairs to augment their surface area. Both the larvae and adults feed on fungal spores.
