I made a weak nuc about a month ago from a trap out to reduce a colony in a wall's strength. It has queen cell added and is doing ok. Had top entrance with an opening 1 inch by 3/8 inch.
Opened it today to do inspection and there is a ball of bees around a dead bumble bee. It was holding on to a frame every firmly and they were tugging away to move it.
That was a tight fit for its thorax and abdomen to squeeze through a 3/8 inch gap. It was about 4 inches from the opening and on top of the frames. Guess it didn't get a welcome party and just couldn't get out fast enough to escape.
