They have no stingers and, if you hold still, so will they. Fascinating to watch, although one did once try to crawl into my ear.

Yep. I hate all flying insects as they make me tense up like some fight or flight response... probably from being stung by hornets a billion times as a kid.

That said, I learned to tolerate the carpenter bees on my deck because they'd bonk all the wasps away.
