Netwinged Beetle Larva ? - Lycus sanguineus

Netwinged Beetle Larva ? - Lycus sanguineus
Skull Valley, (WSW of Prescott 10 miles), Yavapai County, Arizona, USA
May 10, 2008
Found near the ground level in a stack of old used lumber (1896 vintage!). Doubt that the larva are that old yet! : -} Note ventral view also.

Moved tentatively -- thanks, Joe & Robert
Moved from Net-winged Beetles.

this is an extremely interest
this is an extremely interesting northern race of Lycus sanguineus, or perhaps even a new species closely related to it. We need the adults. Maybe Robert Pearson can tell us more about the situation he found it in. I'd like to drive up and check it out...

 
need the adults
Joe: I have previously submitted the adult image for ID. The site where I uncovered these larvae is no longer there as I was undertaking a cleanup and remodeling effort. I have images of this species in ( May thru Aug) 2006, 2007 & 2008. I think I see them every year but don't photo them any longer. Do you want me to capture & save a few adult specimens for further study?

Check out the mandibles.
Lycid larvae have 2 pairs of blade-like mandibles. Eric is correct though, lampyrid larvae are predaceous and lycids feed on various substances associated with rotting wood.

 
blade-like mandibles
Thanks Natter13, but, I didn't retain them.....next time.

Yes.
Yes, most likely. Lycid larvae feed on fungi if I recall, whereas lampyrid larvae are predators that generally don't get along in groups very well:-)

 
Lycid larvae
Thanks Eric
