Any ideas?
[late update - 31 July 2012]
After doing some looking and with some suggestions from a friend, it seems likely that this is an ichneumon wasp (family Ichneumonidae) or similar (family Braconidae). I'm not experienced enough and I can't see the wing vein patterns clearly enough to decide between the two, though I'm told the body is more ichneumon wasp style. Some cursory googling made me think possibly a "yellow-banded ichneumon wasp" (Lissopimpla spp), but there isn't much banding on this one, and I didn't find any similar enough to feel confident that's the right genus. I would still appreciate any further help.
