Common Name: Pacuvius Duskywing, Grinnell's Duskywing
An uncommon species
found in both the Coast Range and Sierra Nevada, mostly in chaparral
and along roads in mesic forest where it often puddles. Confusingly similar to
the Persius Duskywing but always single-brooded, and usually identifiable by
habitat and plant association. It has a gloss or lustre usually missing in the
"matte" persius and lacks a white dot at the end of the forewing
cell above. In fact, it is very dark. Late spring-early summer; host plants
various species of Ceanothus; the reasons for its scarcity are unknown.
