Identification

Adult checkered whites reach sizes of 1.75 in.-2.4 in. (44-62 mm). Sexes are similar and have a chalky white base color on the wings. There are black spots on the upper surface of the wings. On males they are restricted to forewings, but extend onto the hindwings in females. The number of spots differs between the sexes. A characteristic black patch exists along the bottom front margin of the forewing in both sexes of checkered whites. The under surface of the hindwing is a solid off-white color.
