Did you bring your poop parasol?

I love insects.

Thistle Tortoise beetle

These guys are a particular fave…the larvae of the tortoise beetles carry around their own poop like a parasol to deter predators (wouldn’t you be deterred??).

This is the thistle tortoise beetle (Cassida rubiginosa), which is a thistle specialist (go figure!) and the larvae can actually do quite a bit of damage. It is an introduced biocontrol agent that got a little out of control (familiar story?). Now it’s everywhere in North America.

Here’s the adult poking his head out from under his pronotum (a shield that protects him). I caught them during business time.
