Remarks
- Systematics: D.R. Miller reported in Kosztarab (1996) on a considerable variation in several taxonomic characters. Based on this variation, it was considered that E. blanchardii was the senior synonym of this species (Kosztarab, 1996).
- Biology: Living in nest of ant, Lasius claviger, in Massachusetts. Develops one annual generation in USA, Montana (Hollinger, 1916), while Kosztarab (1966) reported two annual generations in Virginia.
- General Remarks: Good description and illustration of the adult female given by Lobdell (1930), Ferris (1950b), Ferris (1953a) and by Kosztarab (1996).
