blue wasp? - Chalybion californicum

blue wasp? - Chalybion californicum
Eugene, Lane County, Oregon, USA
July 29, 2006
Size: 1 inch
I thought this was a cuckoo wasp at first but then when I looked it was larger and did not have black wings. Metallic color all over.

Moved from Sceliphronini.

Probably Chalybion.
I would have to say this is a blue mud dauber, Chalybion californicum, and a female. This specimen is much brighter than is usual, but the drinking behavior would be in keeping with Chalybion. Females are "water carriers" that cart water to the abandoned nests of black and yellow mud daubers (Sceliphron caementarium), and then re-mold the nest by softening the dried mud. Chlorion aerarium, the only thing this could be confused with, most likely occurs only east of the Cascades (I collected a few in The Dalles).
