Unidentified Millipede
Big Bend National Park, Brewster County, Texas, USA

Size: ~2"
Can't find this one in the bug guide or SW Audubon book.

Phengodidae
I see only three legs on this critter's left side. Glow worms can be very colorful. Interestingly, they *eat* millipedes, injecting them with a salivary toxin that paralyzes them almost instantaneously so they don't release their *own* toxins.

From my recollection, this thing was moving quite fast, which leads me to believe it was not a larva. Although I didn't count the legs, it was several inches long and from its speed I assume it had more than 6.
It'll give me a good excuse to go back to Big Bend
