Major commercial hosts:
No major host fruits have been identified but has created occasional quarantine problems.
Distribution
Eastern Australia, from Iron Range, Cape York Peninsula, to southern New South Wales. Introduced to Perth, Western Australia (Hancock et al. 2000). Also in Northern Victoria.
Similar species
Similar to other Australian Trypetinae in having patterned wings, but is the only one associated with edible fruit, and has a distinct wing pattern. Exotic Trypetinae (Anastrepha and Rhagoletis) have very different wing patterns.
Pest Status
Attractant/Lure
Attracted to protein lures and orange ammonia. Occasionally detected at cue lure.
