On another note......
This is a Cuckoo Bee, probably Triepeolus sp. and definitely not nice!
The female lays her eggs in the nests of other solitary nesting bees.
They sort of look like a cross between a bee and a wasp. Usually found hovering close to the ground, sneaking around looking for the burrows where native solitary bees nest, and then like a thief, they slip into the burrow and lay their eggs. The hatched larvae then eat the host's food and parasitize (kill and eat) the host's larvae.
