Symmorphus sp. Symmorphus sp. Wesmael, 1836  

Status:

"S. canadensis is a common species in [Maryland], but it is hard to distinguish from S. cristatus based on images. The latter prefers colder climates so probably most if not all the MD records of Symmorphus on BugGuide will refer to canadensis, except for those from the Appalachian ranges. S. cristatus should be more common there" (Matthias Buck/BugGuide, 6/23/2018).

There are 8 records in the project database.

Symmorphus species nests in Queen Anne's Co., Maryland (5/17/2015). Determined by Matthias Buck/BugGuide. Per Matthias Buck, "Interesting images! This species does not construct mud tubes. What's happening here is likely that these females are reutilizing empty mud nests of another species. This behaviour occurs regularly in some potter wasps (e.g., certain Ancistrocerus) but I am not sure it was known for species of Symmorphus." Photo by Lori Byrne. (MBP list)
