Bumblebee to the rescue!

Ok, not really, but sure looks like that:

And, in support of the "Bumblebees are too dumb to act to rescue one another" theory:

The other day I put a screened tent outside our house. One door was somewhat left open and I come back to find a bee continually bumping against a screen wall.

To help him out, I pull the screen all the way to the side so all he has to do is come to the edge of the wall he's bumping against to get out.

An hour later I come back to shut the screen and find that there is no longer a bee in there. There's 4.

You somehow created an attractive nuisance.  I have a bamboo curtain on the west balcony I drop to shield the west window from the sun.  The flies gathered on that like mad when there were horses in the pastures.

It's been drenched by rain, sterilized by UV, hot, cold, everything you could think of to sanitize it, doesn't smell (to me anyhow) and the flies still thought it was a great fly meeting place.

When I had my shop, I had certain wires hanging down from the ceiling (power to my lathe and the like) and at the end of the day, they'd gather on the vertical wires but not on the horizontal portions of the same wires.

Go figure.

Probably the warmth from the sun attracts them to that spot, with the bamboo getting warmer than the rest of the house's exterior. We have a similar issue with box elder beetles hanging out on the south-west side of the house.
