Checkered White, Pieris protodice <LEP25>
This is a common butterfly of open spaces. Through the seasons it varies greatly in appearance, but it always has a white base with darker markings. Females tend to be more heavily spotted than males. Marks on the underside of the forewings are charcoal-black, while those on the hindwing are olive-green. The drawing shows it taking nectar from spreading dogbane.
