Arilus cristatus (Wheel Bug)
I happened to notice this insect on my car this morning. I’d an immature wheel bug (Arilus cristatus) and I’ve always found them to be kind of cool. The adult wheel bug has a cog-like projection on its back, which is where it gets its common name. The wheel bug preys on caterpillars, aphids, bees, sawflies, etc. so they’re actually good to have around. They do bite, if mishandled (or sometimes just handled) and their bite can be quite painful. So, I’d avoid messing with them, if you have the choice. Just leave them alone and let them eat what they eat.
