Cuckoo bees sneakily lay their eggs in the nests of other bee species, after which their newly hatched prodigies kill the host egg or larva, and then feed on the stored pollen. The host, a solitary bee, never knows anything is wrong. Nine new species of these clandestine bees were recently found in collections and museums across North America, and another six were identified in a decades-old, unpublished academic thesis.
