The frenulum is a row of bristles along the leading (front) edge of the hind wing of butterflies and moths and also in some Hymenoptera such as bees and wasps. The frenulum connects the hind wing and fore wing and makes the two wings act a single surface during flight. It is therefore more efficient.
In bees and wasps the frenulum is sometimes also known as the hamuli.
Other names for (or types of) Frenulum include:
