Unidentified beetle larva

Unidentified beetle larva "drops in" on grad student during a late-night thesis writing session. - Phengodes
Chapel Hill, Orange County, North Carolina, USA
August 19, 2008
Size: 2 to 2.5"
Hi,
I'm a grad student living in someone's basement; this critter fell onto my desk a few minutes back -- approx. midnight -- while I was attempting to work on my master's thesis. Thankfully, it landed behind my laptop instead of on my laptop! It has six legs beneath the front few sections of its body. It looks like some kind of beetle larva, but (much like my data) google, flickr, and other searches haven't yielded any further insight. I suspect it made its way over to the finished portion of the basement from the unfinished portion via the cracks in the wall above my desk. Please help identify this so that I can 1) cease attempts to ID it myself, and 2) more accurately describe the incident to my adviser. Many thanks!

PS. Is there any way to keep this alive humanely and long enough to show some kids? What does it eat?
PPS. The basement isn't as bad as it sounds.

It may be
an adult female. I believe that they eat snails.

 
neat!
Yup, you're exactly right based on those other photos -- thanks to both for pointing me in the right direction. Looks like they eat millipedes and snails.

 
Millipedes only.
They feed exclusively on millipedes as far as I know. Firefly larvae feed mostly on snails, though some specialize on earthworms...This larva should glow brightly, too, so you might try turning off the lights and taking a look.

 
no glow :o(
Hi Eric,


Do the adult larviform females glow to the same extent the larvae do? I tried turning off the lights on several different occasions and never saw her "light up." The only millipede I could find was about the same size as she is; I put it in with her briefly (along with some slugs and snails), but turned them all loose this morning -- didn't want them to die for lack of food.


Thanks anyway!
