Enlarged row of scales on the underside of the tail
Larva
Beside footpath, dead with no obvious injuries, temp 34 F. Was not there previous day. Length 36 inches.
If I had just seen one of these I would have thought it was a garter snake. But there were ten under the porch, where the rat snakes go into the basement. Were they a bunch of garter snakes hanging out or baby rat snakes? I looked up baby rat snakes and they don't look similar.
