As the name implies, this species is a specialist on shrubs in the genus Rhododendron. Currently only known from one site on the Massachusetts border, more targeted searches could turn up additional populations. Early Azalea (Rhododendron prinophyllum) is probably the main host species here, though it's unclear if it also visits planted Rhododendrons.
Identification: Probably challenging to ID from photos without a direct association with Rhododendron. This is a medium-small Mining Bee with long, sparse hairs on the abdomen.
Similar Species: Most similar to several other members of the subgenus Andrena.
Global Status: Not Ranked
Vermont Status: Imperiled (S2)
