Moved from Pedomoecus.

Sorry for the double move -- I'm not sure how that happened.

Moved from ID Request.


Joe, if you can, you should add a lateral view of the head so as to show off the funky spines.

funky Pedomoecus spines
Coming right up...

These guys are cool, aren't they? I've never caught the larvae, but I have a couple adults from a black light trap.

First three images of Pedomoecus
I noticed that in a search for Pedomoecus under 'guide," only the last image (of the head) made it to the guide.

I see four images under [i]Pe
I see four images under Pedomoecus sierra. I did the search on the genus name and only see the one photo there, too. I'm not sure how that particular page gets populated. I performed similar searches on other taxa and got multiple images. Maybe it takes the guide awhile to sort out such things.

The last image you submitted isn't linked to the other three. Is it the same specimen? We should link it to the other photos if so. And sure, if you have a specimen to spare I wouldn't mind one. If not, that's okay -- I bet there are specimens hiding away somewhere at work.

yes, it's a shot of the same specimen as the other three.
Is there some way I should link the head image to the other three?

they're amazing
I was lucky. They really are cool - pretty unique critters. I have one more vial to go through - hope others show up. If they do, would you like a specimen? According to Wiggins, second edition, their unique morphological characters suggests "some specialized way of life, not yet understood." Tantalizing...!
