Here is an interesting post made by Abejaruco, entitled the "war song".
It would appear this moth emits a sound, just like the piping of the queen, that causes the worker bees to freeze, the moth comes in and eats the food, the bees don't do a thing. Interesting. Have a wonderful and most awesome life, day, health. Cindi
