Mason Bees are hilarious bees native to North America that don't fly very well, so they just kinda dive-bomb flowers to get pollen. This is important because that heavy slam (well, heavy for a flower) is enough to distribute pollen into the air. These bees are fat, fuzzy, and winter over by crawling into holes and sealing themselves inside with some mud-spit.

It's VERY easy to create homes for these guys - if you've ever seen someone with a large log that has lots of little holes drilled in it, they were likely prepping a Mason Bee habitat. Ideally, they burrow into hollow, dry grass stems that broke off at some point in the fall.

I try to tell people about this bee because it's so easy to make homes for them. Just make sure to move the home every year, or it becomes too easy for predators to find them.

edit: also worth mentioning this bee is so docile, it usually only stings when it's squeezed or wet, and its sting is very light, and the hook is unbarbed. Better than honey bees in so many ways.
