Found this largish fly about 8mm body length feeding together with a load of much smaller fruit flies on a melon rind I'd left out yesterday (south coast UK) Any ideas? Brian v.  |

Heleomyzidae, [Suillia. Perhaps variegata?

Suillia is OK ! but it is with all probability S. affinis or S. umbratica  Suillia variegata should have haired mesopleuron and a second smaller but distinct vibrissa ! In the female the abdominal tergites are darker banded in posterior part. Cheeks are smaller and distinctly silver shiny !.The area near vibrissae should be dark brown spotted ! FESTINA LENTE

Unlikely to be umbratica (not British). Could also be ustulata - cannot see if the scutellum has hairs or not. |

So, it's affinis ! S.ustulata is much darker (brick-red to brick-brown) with pubescent arista and two vibrissae on each side! and the genae are whitish !
