Juvenal's Duskywing

The Juvenal's Duskywing (Erynnis juvenalis) fly in most areas of the Central, South and Eastern United States where Quercus oak species (the larval host plant) grow.

It is one of many similar looking, brown and nondescript Erynnis species. The white marks on the forewings are larger in females, suggesting the top picture shows a female.

Reports indicate they reproduce one brood per year. However, their north-south range extends from border to border, so they can be active through some part of their range most of the year.
