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...
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 ?
