Phoebis sennae

Common Name:  Cloudless Sulphur

Phoebis sennae

A rare stray from the subtropics, which can turn up literally anywhere - from downtown Fairfield to the high desert in Lassen County. There was a major cluster of northern California records in 1992. Generally flies high and fast, and can be difficult to tell from female California Dogface or Black and Gold Sulphur. Not known to breed in northern California, and no native host plants are present. Females are very variable in color and pattern.
