Parasitic wasps?

[AlienSnail]

As far as I know these prey on insects, though some are parasitic to plants such as the gall wasp is to an oak.

However I am fairly sure I found a black parasitic wasp in with my Megas, and have been trying to identify it.

Could it have got in there to keep warm? or are any wasps parasitic to snails?

I've been looking at the internet for nearly two hours now and can't identify it or find any onformation that suggestes some prey on snails

Is this the sort of thing? I know that some prey on insect larvae www.geocities.com/brisbane_parawasps/index.html

It looks similar to this, only it is entirely black, except with white legs www.geocities.com/brisbane_parawasps/AphidPredator.htm
