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!

Extensions in uppercase are (and were) accepted for gif, jpg, jpeg and png

OK, thanks Roger, now if someone would just ID the fly I would be happy.

FTAO - Gordon; Please make sure that you use lower case, because attachments with extensions in upper case (capitals) are rejected. So sayeth GOD AKA Paul. Cool

A file called "Fly01a" has an UPPERCASE "F" Gordon. The site takes a dim view of UPPERCASE "'F's"!! awkward

OK, it has started working now, no idea what was going on.

I know I have been away a long time - but why can't I load a 63Kb file called Fly01a
