This guy crawled out of one of the mason bee tubes today as I was watching. He was probably stealing provisions and eggs. Unfortunately for him, he became chicken feed shortly after he modeled for this shot.
Um . . . it could be a she. I’m clueless.
Did you pick him (her) up with your hands? Looks mean!
No, I picked him up with a dandelion flower and chucked the whole thing over the fence.
Are bees aggressive to others bees who are not in the same hive?
Yes, honey bees will guard their hive to prevent non-nest mates from entering. They will also fend off other types of insects and even mammals.
Looks like an Earwig you witnessed coming out of the tube.
You are probably right.
