That's for honey-bees, though I've wondered about if Wasps, Bumblebees, or Hornets do similar things.

Anyway, there were no other Hornets in sight, and I got no other visits, or a nest.

Phew! Lucky me! :-)

Thinking about it, I remember sitting outside an Ice cream parlor with friends, having had a bowl of amarena cherry ice. A Wasp flew into it, and almost drowned in the molten residue at the bottom, and couldn't escape the steep and smooth glass walls. I slowly put a spoon into it, to give her a 'ladder'. That worked somehow, but not instantly.

She stayed on the spoon for while, also doing that selfgrooming thing, then lifted off rather uncoordinated, almost crashing into an ashtray, making miniature tornadoes there for a few seconds :-)

Then flying away finally. Also got no 'follow ups', for maybe 15 to 20 minutes, after which we left.

Maybe too exhausted to do that dance-thing, at home?
