Correction #1: Bee Balls ()

I was just listening to podcast #799 and your discussion on the murder hornet. Cara briefly mentioned the bee ball as a defensive measure honey bees can take. But that is incorrect. Only the Japanese honey bees can form the bee ball as a defensive measure to surround and cook the invading Asian giant hornet. The European honey bee does not and is therefore completely defenseless against the Asian giant hornet. That is why there is such a huge concern, as all the commercial honey bees in the US are the European honey bees. Here are some references: Japanese bees' protective behaviors; Meet the "hot defensive bee ball," one of the craziest tactics in the animal kingdom Love the podcast! Stay safe, wash your hands, and wear a mask.
