Synonyms and other taxonomic changes
This species was previously referred to as Vespula austriaca. Recently, Kimsey & Carpenter (2012) showed that North American populations of "V. austriaca" are in fact a separate species, and that the true V. austriaca occurs only in the Palaearctic region. The correct name for the North American species is V. infernalis (de Saussure).
Identification
Key to eastern Nearctic Vespula species in the Identification Atlas of the Vespidae of the Northeastern Nearctic Region (as V. austriaca). (1)
Key to Nearctic Vespinae genera in the Identification Atlas of the Vespidae of the Northeastern Nearctic Region. (1)
Life Cycle
A socially parasitic species without worker caste. Vespula acadica is the known host for this species.(2)
