While watching the bees yesterday eve we saw a bee fly out of the bottom (and only) entrance and drop something on the grass. It appeared to be a half-formed dead bee, it’s skin was translucent and there was a black patch in the middle. It could have been in the pupae stage. Does anyone have any clues as to what it may be or seen that kind of behaviour before?
Could it be a pest which had been growing in the comb and the bee had found it and tossed it out.
