I found this strange fly on a young Citrus tree. Looks like Drosophilidae with very dark wing venation. Minas de Riotinto, February 27, 2023. ¡Saludos!

Ephydridae I think [maybe-ish] and if so possibly a Philygria sp. as a guess [as usual] |

I agree with Roger's guess - but I don't recognise the species.

There are 8 species in Spain: Philygria femorata Philygria flavipes Philygria interrupta Philygria interstincta Philygria obtecta Philygria posticata Philygria stictica Philygria vittipennis Thanks!

Could be Philygria stictica, but the small appendix on vein M is unusual in my experience.

Thanks Tony. Yes , this appendix is strange. Are there more species with this appendix or could it be some genetic error? Edited by Andre Burgers on 01-03-2023 15:28 errare humanum est sed perseverare diabolicum |

In Philygria punctatonervosa there are many short appendices on the veins, and "mistakes" can occur in other species. In Parydra, quite a long appendix occurs on R2+3 in a wide range of species, though it can be absent in some individuals.

So theses appendices are of low value for their identification. Thanks for the explanation! errare humanum est sed perseverare diabolicum |
