Tropical Monkey Slug

Phobetron cf. hipparchia


A hairy spiny caterpillar with fleshy appendages on both sides.


Found on the old rust covered leaves on an avocado tree. It's color seemed to be a perfect match for the leaf rust, making it very well camouflaged (see final image in the series). Based my ID on comments made in this spotting of a very similar caterpillar, --Update-- The next day I found the caterpillar had molted and changed it's appearance quite a bit. For those interested it can be found here,

Thanks for the comments.
Update: After talking to a local, he said these caterpillars aren't the ones that give you a nasty sting. But rather the ones to avoid are the ones like in this spotting,
