Checkered White (Pontia protodice) is a medium butterfly, with a wingspan of 1.5 to 2.5 inches. It can be seen from March to October. Locally, numbers peak in June-July-August. Like Cabbage White and Margined White, it has many host plants in the mustard family (Brassicaceae), including cabbage, cauliflower, Brussels sprout, turnip, and broccoli. Caterpillars will eat leaves also, but buds, flowers, and fruits are preferred.
This butterfly, like all butterflies in the Pieridae family (Whites and Sulphurs), flies endlessly and does not land very often. So it is under-represented in photograph-based databases like iNaturalist.
It is found primarily across the US and Mexico, but there are some sightings from the southern part of central Canada and some from Central America.
