There needs to be metal band called Vulture Bees, this is too metal.

On bed of mottled rocks 
Amid flowers cold as ice 
Pray the weak, the old, the poor

And when the tiny one from Heaven comes 
Crawls inside the chosen skull 
And when the tiny one it summons the others 
To crawl inside the chosen skull

They build their castles in the heads of kings 
Bring life to the empty halls 
They build their castles in the heads of kings 
And honey will flow once more 
Once more

A protein stache would be part of a meat beard.

Fascinating. It's worth mentioning that (normal) honey can be used to preserve meat, thanks to its antimicrobial and hydrophilic properties. I guess that's what's going on here too: they use a kind of nectar honey to keep the meat component from going off. That said, this kind of food preservation isn't immune to botulism so do be careful if you try this.

Now I'm wondering when/how this behavior evolved. Did these guys come first, and honeybees figured out how to eat pollen as a protein source as an evolutionary step, the other way around, or separately at the same time from some parent species?

No it's my Meat Puppets cover band
