I found this strange fly on a young Citrus tree. Looks like Drosophilidae with very dark wing venation.

¡Saludos! |t

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

---

Your guess is my certainty. :)

My first photos of a specimen belonging to this family. |t

Thanks, once again, Roger!!!

---

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

---

Perfect, Tony! I can remove this 'possible'.

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

Thanks! |t

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?

---

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. |t

Thanks for the explanation!
