Nomenclature
Originally described as Bibio lucifer by Fabricius in 1775. The Poecilanthrax was last revised by Painter & Hall (1960), who recognized 35 . The genus is strictly North ( lato) with greatest abundance in the Great Basin region.
Voltinism flexibility
While most Poecilanthrax are strictly , P. lucifer shows ecological flexibility in agricultural environments where multiple may occur due to continuous availability.
