R.D. Wheeler has it right. We use to do alot of hunting on FT. Hood for rabbits, squirrels, armadillos and such. In the warmer months the rabbits would oftentimes have a Wolve (That is what we call them also) just under the skin of the armpit.
They look like a giant brown maggot:barf: about the size of the last joint of your thumb!
We always left the Bunnies so infected in the field.
