Hello, I have had quite a lot of these flies (30 at least) found most dead on the sisal carpeting. The room is almost empty, only 2 wooden cupboards, a chair and a lamp. No food in the room. Do you have any idea what kind of flies these are? They are about 5-6 mm tall, light brown, dark eyes. Best regards and many thanks Connie https://insektenf...f8ab96ec75 https://insektenf...f8ab96ec75 https://insektenf...f8ab96ec75 https://insektenf...f8ab96ec75 Edited by connie on 23-09-2020 00:26 |

The presence of dorsal pre-apical bristles on the tibiae suggests Lauxaniidae. Tony ---------- Tony Irwin |

Costal setae appear to be reaching M1+2 so genus Homoneura.

Hmm... could be... what do you think, why do I have so much in short time at one spot? |

As far as I know, the biology of most Homoneura species involves feeding on decaying leaves. It may be that these flies have spent the summer as pupae, and are emerging now to take advantage of the new crop of leaf litter. Difficult to say exactly where they're coming from, but I would suggest that they are probably attracted to light, and coming through a window.
