Hello, Is this fly a Bithia ? May be B. acanthophora ?

Thank you very much ! In this key, it's written that B. modesta doesn't have marginal bristles on T2. Mine has no ? I see two dorso marginal bristles Edited by Jessica on 04-02-2024 19:33 |

Jessica, so the first two segments are merged, called syntergite 1&2. That makes tha apparent second segment actually the third. So syntergite 1&2 has ni marginals here. https://uk.inaturalist.org/taxa/321744-Bithia-modesta Theo Edited by Zeegers on 06-02-2024 16:40 |
