It has been recorded in Belgium and Canada (Calgary), suggesting a transatlantic distribution pattern. As a member of Theronia, it is presumed to be a parasitoid, though specific associations for this subspecies remain undocumented.

Identification
Distinguished from other Theronia by the fulvescens (tawny/yellowish-brown) coloration implied by its subspecific epithet. The Theronia is characterized by distinctive wing venation and body proportions typical of the tribe Theroniini. Specific diagnostic features separating T. a. fulvescens from the nominate subspecies T. a. atalantae and other subspecies require examination of coloration patterns and structural details.
Distribution
Recorded from Belgium (including Brussels-Capital, Flemish, and Walloon regions) and Canada (Calgary, Alberta). The disjunct distribution between Europe and North America suggests either natural range, introduction, or potential misidentification requiring verification.
