They belonging to the family Ptiliidae which is referred to as feather-winged beetles as the hindwings are narrow and feather-like. Like most of the rest of the family, ''Pteryx'' are very small and live in rotting vegetative matter. They prefer rotting wood and are generally found under the bark of rotting logs or stumps. ==Description== The ''Pteryx'' are less than 1 mm in length. They are polymorphic, in that they frequently occur in two forms, a normal variety, and a neonate form that has only vestigial wings, pale body pigmentation, and no pigmentation in their smaller eyes.〔Dybas, Henry S.
