Species notes

The holotype of A. abrupta was destroyed, so a neotype was desingated by Brooks (1988). Smith (1854: 339) suggested that his species was likely the female of A. abrupta.



Frison (1922), Rau (1922, 1929), Norden and Scarborough (1982), Norden (1984) studied aspects of nesting and life history. Frison (1922) that this species nests in large aggregations, and winters as a mature larvae. Though the species typically will nest in vertical banks, and artifical clay nests (Graham et al. 2015), it will also used the soil surrounding uprooted trees (i.e., root plates) (Campbell et al. 2017).



Cresson (1879) indicated "Can." as part of the distribution for this species, though provided not further details. Brooks (1988) also recorded this species from southern Ontario and Quebec.
