Leaf-cutters

Megachile genus leaf-cutter bees cut out circles of leaves to line their nests.

Another characteristic of this huge genus is that they carry pollen on the underside of their abdomen. So that glow you see is actually pollen in the hairs. Honey bees, bumble bees, and other bee species typically pack it around their hind legs.
