OK, update on summer leafcutter mason bees. They are hatching, I think i see them in my garden. Hard to tell, as they are about honeybee size. Not one of them has put a cocoon in my very expensive chalet. They have to be putting them somewhere nearby, however. Maybe next year they will. My opinion of the mason bees would be to skip the spring time bees, as the veggies aren't blooming then anyway. At least here in TX. That leaves the leafcutter bees. My garden has much more veggies than last year.
