How small are dustywings compared with other lacewings?

Dustywings, which belong to the family Coniopterygidae, are significantly smaller than most other members of the order Neuroptera. While many other lacewings range from medium to large sizes—with some species, such as moth lacewings or owlflies, reaching wing expanses of 50 mm to 100 mm—dustywings are tiny, with a wing expanse of only 3 to 10 mm.1

Unlike many of their relatives, dustywings are also distinguished by their bodies and wings being covered in a white, waxy powder.1
