Dear all,

Second Tachinid question for tonight:
Here is a small specimen I identified as a Phasia following Central europe key.
From side of Loire (ending of the Layon river, for those who are interested in Diptera and vine Smile), wet area.
Several specimens, I also caught a female (and I have picture in vivo of her)

I totally dont get the first point of the Phasia key, so I followed both.
Ibelieve it could be P theodori as:
-halteres are yellow
-hairs on peristome are totally white
-S7 of female appear similar to the figure given.

My little doubt are from the wing of male: It has is centraly black tinged (not greatly visible on this picture I am afraid).
And wing is mention to be unspotted. So I am wrong?

I apologize for quality of pictures, specimen is really small!

As you noticed, wing colouration is off, moreover, it is too big.
Are you sure it is Phasia and not Ectophasia ? When Phasia, obesa is the first species to check. Female genitalia are highly distinctive in Phasia.

Your right, this is Phasia obesa...
In the mean time I caught a P pusilla: I now understand the "hairs on parafacial" critera!
many thanks for putting me in right direction!
