I have ants pollinating my peaches and blueberries.
Also carpenter bees and miner bees. Wasps and small flower bees are abundant later.
If honeybees grow to a natural size, either wild or on natural size comb, they do better at grooming and removing mites. Most commercial frame comb is a little larger than natural. Or so I have read.
Peonies are one of my favorite flowers. They’ve always got ants crawling all over them ;-)
I haven’t raised bees, and didn’t know this stuff; but found this (?)
