Not sure? The lookalikes

| vs drain fly | drain flies have broad, fuzzy, heart-shaped wings held roof-like over the body, unlike the clear, flat wings of fruit flies |
| vs phorid fly | phorid flies have a distinct humped thorax and move by running rapidly rather than flying, unlike the primarily flying fruit fly |
