Saw this today in Milton, GA-he has a purplish underbelly. He moves like an inchworm, sort of. He’s pretty aggressive-flopped around as I was trying to get a photo.
This is an Underwing Caterpillar from the genus Catocala, possibly Catocala ilia which is pictured on BugGuide. Many Underwing Caterpillars are good camouflage artists, mimicking lichen covered twigs.
