Neriidae are slender, long-legged flies. Many species are sexually dimorphic, with males having more elongated bodies, heads, antennae and legs than females. Neriid flies are saprophagous. Larvae develop in rotting vegetable matter, including bark and fruit. Neriid adults tend to aggregate on rotting vegetable matter or damaged tree trunks. Neriid adults are also attracted to flowers, or other sources of sugar.
Neriidae is a relatively small family of true flies (Diptera) with long, stilt-like legs. Most species are found in the tropics. Neriids have very interesting behaviours, and many species are strikingly sexually dimorphic, with males having much longer legs, heads and/or antennae than females. Like piophilid flies, neriid larvae have the ability to leap during the stage just before pupation when they migrate from the larval feeding substrate to the pupation site. Very little research has been done on this interesting group of flies.
Males of some species engage in spectacular combat for territory or access to females. The rivals elevate their bodies to an almost vertical posture, and pound each other with the ventral surfaces of their heads, strike each other with their forelegs, or try to place each other in a head-lock.
