Frangipani hornworm caterpillar

animal, Key West Field Guide

Pseudosphinx tetrio

Although most people who walked by while I was admiring this caterpillar shared the wonder of such a gigantic, colorful creature by taking photos and watching it wander down the sidewalk, a few imparted more negative opinions. One informed me that it would bite me (it didn’t). That it would burn me like “muriatic acid” (it didn’t). And a third suggested I would catch a disease (haven’t appeared to). But none of these people knew the name of the caterpillar or even what it fed on. After identifying this larva online, I transported him to the nearest frangipani tree about 200 yards away, which had about 5 other Pseudosphinx tetrio caterpillars munching on the leathery leaves. Moral of this story- assess the risks and decide for yourself. If it has a mouth, it can bite. (I’d probably survive.) It could sting. (Again, I’d probably survive, but it is something to consider in advance.) And truthfully, if I got sick from a caterpillar, I’d probably think it was worth the novelty. (And I’d probably survive – and I’d definitely share the tale with others.)

And for true excitement, topped only by watching paint dry, some video of the caterpillar munching on a frangipani leaf.

It never fails – find a hairy caterpillar with kids and they always claim that it’s “the one that stings!” To be fair, this one was virulently green with black-tipped spines and a bold red stripe- it certainly looked a bit dangerous. Never having met this beauty before, however, I decided to test the theory.
