Tephritidae: Picture-winged Flies

There are some flies in other families with similar wing patterns, such as Trypetoptera punctulata.


Anomoia purmunda (Harris, 1776)

Anomoia purmunda Anomoia purmunda Cambridge, Gwydir Street, 24 Aug 2014.

Length (head + body) 4.5mm; wing span 10mm

This family of fruit-flies or "Picture wing" flies includes some which are serious pests such as the Med-Fly Ceratitis capitata.

In this species, the wings are carried in this front facing posture, perhaps as an attempt to look bigger or fiercer than it really is. The markings look vaguely spider like but would this really fool a potential predator? Maybe it is a mating display ...

Synonym: Phagocarpus purmundus

NBN Atlas.
