Explanation of Names
Sceliphron curvatum (F. Smith, 1870)
Identification
According to Christian Schmid-Egger (Aug 12, 2019: pers. comm. to Matthias Buck), the photos on Bugguide clearly show S. curvatum, not S. deforme (up to this point there was doubt about the species). Schmid-Egger (2005) provides a key to separate the two species from each other and from European species [in German].
Range
limited scattered US records - Map (1); native to Asia, introduced to Europe where it has been spreading rapidly. Also introduced to Argentina where it was first discovered in 2001 (Compagnucci & Roig Alsina, 2008).
Remarks
BugGuide photos from Quebec (2013) apparently represent the first North American record for S. curvatum.
