This is a sneaky weed. I’ve walked past it dozens of times, always waiting for it to flower. It wasn’t until a friend brought me specimen from her yard that I discovered that the tiniest flowers dangle underneath the leaves. Find more info here.

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.

This is actually the second time that I’ve posted this species, but this post shows shows how to identify it according to the Guide to the Vascular Plants of Florida.
The key difference between this species and its other Florida relatives, P. lanceolata and P. fruticosa, lies with the leaves.
