Spiny caterpillar on azalea bush
I found these caterpillars on my azalea bush this morning. There were probably 15 of them. I have never seen them before. As I was putting them in a container, one fell on my hand and I had a burning sensation on the area. Are these poisonous? I live in St. Petersburg FL. Thanks for your help.
There may be slight pain and irritation from contact with the spines of the Io Moth Caterpillar, Automeris io. The adult moth is a lovely “eyed” Saturniid.
