Most Florida caterpillars will sting.
I was stung once as a teenager mowing the lawn, brushed by a bush that had one on it.
It was like someone set my entire arm on fire!......................
I assume they ALL sting. I’m in S.E. TN and I think we have them here. A few years ago I was stung by some kind of caterpillar that sent me to the E.R. If I’m working around bushes, etc. now I wear long sleeves and pants.
