Eastern Black Swallowtail (Papilio polyxenes)
Do you have any idea if that 'black' caterpillar is the same kind as the others?
I've had several Eastern Black Swallowtail cats, but I've never had a black cat before.....
Cool.
Happy Summer.
Yes, they are both Black Swallowtails. That was the reason I took the picture to document what they looked like. I have only had the one black one. Others on Dave's said that they had seen it happen ever now and then too, but no reason that they could give.
