I removed a small nest from my door frame a few months ago and one larva fell out. It landed on the hot concrete in the summer sun. I empathized and picked it up. I kept it in a jar with a paper towel under a lamp. I checked on it everyday and I thought that someday I’d set it free in my yard. I even daydreamed that it would immediately sting me when I let it go and that just made me laugh a bit. It eventually died and I put it on my bird feeder. I didn’t watch and ai felt sad but it’s gone now.
