I would suggest that the Black Swallowtail caterpillar is eating his old exoskeleton...

By the way, that is a rather unusual coloration for a polyxenes asterius...

Subject: ID Help

I was at Dead Creek WMA   Brilyea access road back by the turtle pond and found these cateplars and would like some help.

First,  can anyone ID the brownish hairy caterpillar ?

Second,   what is the correct way to describe what is happening in the image of the Black Swallowtail caterpillar ?
