Green Long-legged Flies - Subfamily Sciapodinae

Family Dolichopodidae

This page contains pictures and information about Green Long-legged Flies in Subfamily Sciapodinae that we found in the Brisbane area, Queensland, Australia. They are also known as Dolichopodid Flies.
 
Long-legged Flies in subfamily Sciapodinae can be recognized by the wing veins, the excavated vertex on head and the special metallic green body colour. Male Long-legged Fly has the 360 twisting of the postabdomen.

They are predator. Adult Dolichopodid Flies' mouthparts are modified for predation, but not elongated. They feed on smaller soft body insects such as aphids. We usually found those Dolichopodid Flies resting on large leaves. They can also be found on tree trunks, mud flats and river rocks. 
 
Larvae are maggot-like. They are usually found in moist soil and under tree bark. They are either scavengers or predators of other insects larvae.
 
Followings are those Long-legged Flies that we found in subfamily Sciapodinae. They are generally recognized by the branched vein M1+2 and excavated vertex, is the largest Long-legged Fly subfamily in Australia
