Explanation of Names
Sceliphron curvatum (F. Smith 1870)
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].
native to Asia, introduced elsewhere (scattered US records [map](1)); spreading rapidly in Europe, discovered in Argentina in 2001 (Compagnucci & Roig Alsina 2008).
BugGuide photos from Quebec (2013) apparently represent the first North American record
