It belongs to a strictly North American of flies whose larvae develop inside caterpillars, primarily cutworms and armyworms (Noctuidae). The genus Poecilanthrax contains approximately 35 species, with greatest diversity in the Great Basin region. Specific details about P. alpha's and distribution remain limited in published literature.

Taxonomic Note
Poecilanthrax alpha was described by Carl Robert Osten Sacken in 1877. The name derives from Greek 'poecilo-' (variegated/pied) and 'anthrax' (charcoal/coal), likely referring to the coloration patterns typical of the group rather than the anthrax. The specific epithet 'alpha' is the first letter of the Greek alphabet, though the reason for this choice in the original description is not documented in readily available sources.
Related Species Biology
While specific details for P. alpha are unavailable, congeneric such as P. lucifer have been well studied. These related species exhibit (one per year) in natural , though some become facultatively or multivoltine in agricultural settings where pest caterpillars are available for extended periods. Larvae parasitize noctuid caterpillars including fall armyworm (Spodoptera frugiperda), with rates reaching up to 25% in some .
