Dear Lisa,
This is a solitary bee in the family Megachilidae, commonly called Mason Bees or Leafcutter (or Leafcutting) Bees.  According to BugGuide:  “Most are leaf-cutters, nesting in ground, in cavities, wood. Tunnels are bored in wood or in the ground. Cell is provisioned with pollen (and nectar?), an egg laid, and cell is sealed over with circular pieces of leaves that fit tightly into cavity.”
  According to Featured Creatures:  “Most leafcutting bees are moderately-sized (around the size of a honey bee, ranging from 5 mm to 24 mm), stout-bodied, black bees. The females, except the parasitic Coelioxys, carry pollen on hairs on the underside of the abdomen rather than on the hind legs like other bees. When a bee is carrying pollen, the underside of the abdomen appears light yellow to deep gold in color.”  WE are sorry to hear about your daughter’s sting, as this is not typical of encounters with Leafcutter Bees.

Thank you so much for the info! I am sure it just felt threatened as it would have been squished if my daughter grabbed the chain any harder. Thanks again!!
