Response Statement - Eastern Persius Duskywing
This lupine-feeding butterfly has been confirmed from only two localities in Canada. It inhabits oak savannas in southern Ontario, a habitat that has undergone substantial declines and alterations. Larval host-plant populations have been greatly reduced. There have been no confirmed reports of this butterfly since 1987, but there have been no intensive surveys for the species since 2003. This, combined with its similarity with other duskywings, makes it possible that it still occurs but has been overlooked.
