Muscid Fly (Male)

Phaonia sp.


Coppery-brown-orange fly, about 10mm in length. It has clear wings, reddish eyes, grey thorax with black stripes. It could be a Phaonia sp. It looks very close to Phaonia subventa, but P. subventa is distributed across parts of the Palaearctic, not in the Oriental region. Phaonia Robineau-Desvoidy, 1830, is a very large genus from the fly family Muscidae, of order Diptera. The orange body, stripy thorax, which is grey above and orange below, and the bulge on the outer wing help to identify it. The female has varying amounts of black on the abdomen. The sexual dimorphism in the eyes is striking, holoptic (eyes meeting) male and dichoptic female.


Backyard, spotted on a Gabi (Taro) leaf.
