Hello everybody,

It could be the Pollenia griseotomentosa? It has been collected on 27-03-18 in Majorca.

Thanks in advance!

chaetotaxy, facial keel and other features doesn't match griseotomentosa group (griseotomentosa and mayeri).

could simply be a femle rudis but i'd need to see the ovipositor to be certain. many Pollenia range from 6mm-to-11mm, so size isn't necessarily an indicator for a species.

if you really want an id, you can always send it to me.

Thank you very much for your help.

There are some pics that I have taken:

i66.tinypic.com/20qnr4j.jpg

I'm a little bit confusing, because I only see one presutural supra-alar seta (instead of two=rudis group)

following link is a foto of the head of griseotomentosa in profile:
https://c2.static...2457_h.jpg

keys for the female from Dr. Rognes:
f2 with one ad, frontal vitta is black with a reddish color toward the lunula
abdomen with a dark median stripe widening posteriorly
eye in profile much higher than gena

you must be looking at the ia. ac - to - dc - to -ia - to -supra-alar
supra-alar seta
https://diptera.i...amp;id=291
http://i68.tinypi...h2h7ye.jpg

outer ph setae are used by Dr. Rognes.
furthermore, i believe that i see two ad mid tibia. is this correct?

without viewing the ovipositor, i cannot suggest a species.
i will attach a photo of mine depicting the ovipositor of P. rudis for reference
