Dang! At first I kept thinking wtf, why is this guy taking apart bee nests... but in the end we see why: Looks like I'll have alot of Bees that will emerge in the Spring. Hope my care for them will be good enough. Phew!
Twenty years ago I used to see lots of mason bees here in the Midwest. Now I almost never see any. And I've never come across a nest. Bald hornets, mud wasps, yes, they're all over, and watch your step or you might walk into those underground yellow-jacket nests. Where are the honey bees, bumblebees and mason bees hiding their homes? I wouldn't harvest honey, but I'd do what I can to safeguard their habitats.
Thanks for an awesome post, @solominer!
