Thread subject: Diptera.info :: Ant mimic wasp ?

Put a little honey/sugar water on a milk bottle top near the nest of a black ant colony the other day. I didn't get a huge number of takers but decided to photograph 2 "ants" on opposite sides of the drop. Much to my suprise one of the ants turned out to be a flightless wasp which I think is Gelis sp.
Anyone know of any biological link between the two ?
I was suprised to see the wasp (only seen 2 others in 5 years of macrophotography) and the fact that it was so close to the ant without the ant taking any notice (they are normally aggressivley territorial to other insects).

It is Gelis agilis, a parasitoid of various small insect cocoons in open habitats. Adult females overwinters.

Thanks for the ID Camille
Yes you can certainly use it in your gallery - you can find a larger version here http://www.flickr.com/photos/lordv/4411348270/sizes/o/ if you need it
Would the wasp overwinter with the ants ?

By the way I have some nice shots of what I assume is another Gelis sp. here http://www.flickr.com/photos/lordv/sets/72157594222560020/detail/?page=29
