This caterpillar is much less of a safety concern, at least to us humans, though it will still cause a rash if you touch it. This is due to the spiny tuberclues along the back and sides with spikes known as ‘calltrop’ spines, found in three pairs of large horn-like spines at the front and two pairs at the rear. You'll typically find these 3/4-inch crawlers in oak and willow trees, as well as beech, cherry, maple and other deciduous trees.
