Here's a detail of another one a little farther along in development. This one was trying to climb out of the sample jar. Six legs with very pointy hooks, head and jaws more developed.

Hi Michael, The first one is a Soldier Fly larva (Stratiomyidae). http://www.freshwater-science.org/educa ... cro110-jpg

The second one is different. Without seeing more of the larva I would suspect a beetle larva, in particular a Diving Beetle (Dytiscidae).

The owner of the pond, who is a fisherman, suggested Helgrimite as a possibility.

For the second one check out hydrophilid beetle larvae.

Not saying this is the species... but this is a pretty typical appearance:

Thanks, loads, Charlie. Yes, indeed, it is a diving beetle larva.
