Regarding the glow worm you found:
English names cause much confusion. Your worm may be a lampyrid larva/flightless adult, a phengodid larva/flightless adult, or possibly even something else. Each of these animals has rather different care needs.
I suggest you post a pic on Bug Guide so their experts can identify it.
I'm fairy certain what I have is a Pleotomus sp. larva, either that or Microphotus, but my bet is on Pleotomus.
Once I get a little more time, and some better pictures I will start a thread about it, it's a very neat critter. I've had it about a month, and I've been feeding it snails. (hunting for snails in locations where there's not likely to be pesticides in the panhandle of Texas, during the winter is a fun activity for all ages!) It seems to be doing well, and has molted once in my care.
Thanks everyone for the warm welcome!
