Ostracod under the 'scope

So, I recently got an Arcturus Labs "Magnifi" iPhone case/microscope adapter mount in order to more easily take photos using the microscopes at school. This morning, I managed to grab some decent photos and a bit of video of an Ostracod. Check it out:

And the video:

Neat! 

Help me identify this wasp(like insect), please.

This guy was riding the bus with me the other day. It looks like some kind of wasp, but I've never seen one like this before. It was about 2cm long, including antennae.

Any ideas?

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.
