They're very skinny white worms
Four or five of these were crawling about on the bottom of a small artificial freshwater pond.
Not sure what the host insect would have been, but there was a big dead cockroach Drymaplaneta sp. in the pond.
Poor nematode! He got stuck on some organic matter -- he is really having a bad day! The coordinates for this observation are inaccurate and have to be re-done.
Nematode which is squirming dramatically.
On a fallen log in podocarp-broadleaf forest. Waving front portion of body around, then crawled down to ground. About 100mm long.
