Palmetto tortoise beetle larva

Hemisphaerota cyanea

Description:

The larva is covered in a straw-like mass called 'frass', aka feces. (see Notes)

Habitat:

spotted on palmetto frond in scrub land sanctuary

Notes:

Upon hatching, the young larva begins to excrete strands of dry feces that curl up over its back and accumulate to form a dense thatch-like shield. Larvae have an anal fork to hold the fecal shield in place. The fecal shield has been shown to be an effective defense against a predacious larva of Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae) and the predacious stink bug, Stiretrus anchorago (Fabricius) (Hemiptera: Pentatomidae). However, the carabid beetle, Calleida viridipennis (Say) (Coleoptera: Carabidae) is able to penetrate the larva's defense by chewing through the shield or by getting underneath it and prying it up

Truthfully I dismissed these photos as 'just some stuff' on a palm. But in looking for another ID, I happened upon the reference link attached to this spotting. I thought I may have deleted the 'stuff' files, but finally found them. So, Ashley, I had no clue; but have learned not to delete even the most obscure photos. And Gilma and Yuko, the amazing thing is what can be learned from the PN community. Thanks for your comments.

Great spotting! Who would even imagine (other than the PN experts) that this is actually a beetle larva!?

How did you even figure out this was an animal??

I thought it was pretty incredible, Mayra; this was the first time I'd ever seen one.

Think about, they go through a great part of their lives covered with poo...

A pretty extreme survival strategy to be sure. At least giant swallowtail caterpillars only 'look' like poop.

This is by far the strangest thing I've discovered in the scrub--really exciting.
