Notes. Holarctic. Social ground-nester, but displays polyethism, reverting to solitary behavior at high latitudes and altitude ( Eickwort et al. 1996; Field et al. 2010; Potts & Willmer 1997). The nesting of this widespread species has been documented across North America ( Atwood 1933; Eickwort et al. 1996; Hicks 1926; Knerer & Atwood 1962; Soucy 2002; Yanega 1988).
