Tim
You're getting all the Dytiscid larvae cleaned up. You should email John V to become an editor so you can see the images in larger format, like the 750 for this one, than the 560 size shown.

 
Criteria for becoming an editor
Just curious to know what it takes to be one...

 
Criteria
I'd think that it would be good if you mention your field of expertise, the contributions you've already made to help the guide, and what ways you want to contribute in the future. Many of us editors have no real expertise in any particular field, but are passionate about making bugguide the best we can. Using sound judgment, and keeping up with what's going on by reading the forums helps. Here's one of the forum topics that touches on becoming an editor.

Moved
Moved from Beetles.

 
Subfamily Hydroporinae for sure
can't tell below that...Larvae of this subfamily can be characterized by the frontal projection or "horn" between the mandibles and generally small size..genus id is difficult, requiring detailed microscopic examination of features such as the mouthparts, abdominal segments, setae, and cerci

 
And what do you know...
it's Neoporus..after going through Larson's larva key :-)
There was alot of squinting though..trying to spot particular hairs or setae

Dytiscidae
The genera of dytiscids are pretty well worked out, but it would require someone interested in them to arrive at that point. Gyrinid larvae have lateral abdominal filaments like Megaloptera.
