Genus: Philomycus
Light brown, over 3 inches long.
Rural SW Pennsylvania
Here's an excellent reference. http://ufdcimages.uflib.ufl.edu/UF/E0/04...
My vote is P. flexuolaris. The blothy spots with random interconnecting lines are exremely common in P. flexuolaris. Actually I feel pretty confident with that Id.
The source I used only showed P. carolinianus and I took premature leap of faith.
I'm not sure if it's P. flexuloaris, P. carolinianus, or M. mutabilis. They're all fairly tough to suss out, especially from photos. You should check out: http://www.carnegiemnh.org/mollusks/pala...
This is a Philomycus species- a native slug to N. America. Limax m. is a European invasive.
