On another thread in the Queen breeding forum the subject of cannibalism came up and it occured to me to post this. I watched a queen emerge in my observation hive this summer. She promptly ran to a capped drone cell which either she, or the workers following her, opened up. In the melee I couldn't tell for sure who did the work, but shee seemed to be trying to uncap it. She obviously ate either the jelly inside or some of the drone pupae itself for some time. Then she went looking for other queen cells to kill.
I was wondering if anyone else has ever seen this? It was interesting. She acted quite hungry and this seem to satiate her, but I'd never heard of this behavior nor seen it before.
