I can’t even tell what family this bug might be in. Sorry, don’t know where he was except found on a hike in the ‘wilds of the Catskills’. There are two red dots. The science teacher who found it & wants to help his students ID it says it looks like a cross between a roly poly & an inchworm.
This is a photo of the Crowned Slug caterpillar. The later instars have the red dots. The adult is a moth.
These are found in the woods. Larva feed on leaves of many trees especially oak, but also cherry, hickory, maple, basswood, beech and elm. They overwinter as larva.
This is one of the stinging caterpillars – the bristles are filled with poison to defend themselves from predators.
