Today, aug 22nd, a Tachinidae appeared out of a cocon of Arge ochropus. The Arge-larvae pupated july 29th.
More info about the observation of the Arge -sawfly, you find here: http://waarneming...1?_popup=1

Dag John

Mooi werk, met een goed gedetermineerde gastheer !
Nu de sluipvlieg nog. Het is een vrouw Compsilura of Vibrissina, ik kan het niet goed zien. Kan je mij een hires sturen van het dorsale shot (stuur me een PM voor mijn email).
Of beantwoord zelf de volgende vragen
* ogen kaal of lang behaard
* ocellaarborstels aan- of afwezig
* dorsocentralen 3+3 of 3+4 ?


Thanks


Theo

Heb je een PM gestuurd Theo.

Had already a Vibrissina turrita few weeks ago from another sawfly-larvae. For me as a non-dipterist that one looks different.

So, I got the fly (thanks, John!) and it is a female of Vibrissina turrita, thoug aberrant.
Vibrissina turrita is specialized on Argidae and Tenthredinidae, so that makes total sense.
