These five caterpillars are probably the scariest ones out there - some caterpillars you'd love to pick up and have crawl around in your hand, but not these guys. All of them are poisonous, so watch out! Hopefully, they will scare you away with their frightening appearances before you get close enough to touch them!
My favorite is the Cameron Caterpillar - the last one in the gallery. It looks like a fuzzy stick with sharp barbs - what an insect!
