Leaf cutter bees complete your pollination season. They Hatch in the summer after the early and late spring masons have finished thier life cycle. The leaf cutter is quite an amazing creature. They will cut perfect circles in leaves and bring them to thier nest. They will wrap thier eggs with them. They look like mini cabbage rolls. The leaf cutter really like rose pedals. When you open up thier nest and see all the different colors, it truly is, natures beauty at its best.
