One of the last species to emerge in the fall, most likely in early to mid September. Currently only known from two 2019 records in Chittenden county, but perhaps overlooked given its late flight window.

Identification: This is a large species that lacks the red on the thorax of other Cellophane-cuckoos.

Similar Species: The large size and lack of red make this species superficially similar to Long-horn Cuckoo Bees (Genus Triepeolus).

Known or Suspected Hosts: Aster Cellophane Bee (Colletes compactus)
