Thread subject: Diptera.info :: Tachinidae - Phasia aurigera parasiting Rhaphigaster
#1
In march a bug visited my desktop - no doubt Rhaphigaster nebulosa overwintering. One day later the bug dies and I found a diptera larva near the bug, which I layed in a wet paper hankerchief in a small box. Two weeks later I found this Tachinidae (unfortunately dead). Would be nice, if I could add a name to the photos in our bug gallery. Thanks in advance Frank

Rhaphigaster visiting the desktop.
One day later: surprise!
Two weeks later: Species?

Ectophasia crassipennis?, Phasiinae.

Thanks, this would be a suitable solution. E. crassipennis is one of the most common species here. The following specimen I found in our garden a few weeks ago. E. crassipennis too? Best regards Frank

Wonderful series of photos Frank
The first (your bug parasitoid) looks like a
Phasia sp. but it's not one that I am familiar with - note the long petiole. See this page of
Ectophasia pics:
http://tachinidae...rcno=15901, which has no petiole.
The second is harder to judge because I can't see the wings very clearly but it does look quite like an
Ectophasia sp.

Amazing !
It is near Ectophasia,
actually it is a female of Phasia aurigera (the topcell is stalked, thus Phasia). It is quite like Ph. hemiptera, the more common species, however, the legs are all black and the reddish hairs on thorax are absent.
Phasiinae are relatively rarely bred. So this record of a less common species is quite interesting.
Thanks

Thank you very much for your help - and prey

If I follow your explanaitions the specimen in Septemer should belong to two species - right? I add a second view of both for illustration. Thanks in advance Frank

Correct.
Above is a male Ectophasia, most likely E. crassipennis.
Below again the female of Phasia aurigera.

H.-P. Tschorsnig (Stuttgart) just informed me that the host was already given by Dupuis.
So no new host record, still interesting.
