thumb|right|wing venation (male)
The Lonchopteridae (spear-winged flies or pointed-wing flies) are a family of small (2–5 mm), slender, yellow to brownish-black Diptera, occurring all over the world. Their common name refers to their pointed wings, which have a distinct venation. Many are parthenogenic; males are very rare, however, at least in North American species, and have a somewhat different venation than do the females.
