Becker's White

Becker's Whites can be an easy and worthwhile butterfly rearing project for those who live in the Great Basin, Colorado Plateau, the Western Slope of Colorado, as well as the more xeric areas in the Pacific Northwest.

In these areas where Becker's Whites fly well, one can easily rear this butterfly either by collecting a live female and caging her for eggs (see video) or by looking for larvae on any of the mustards this butterfly uses.

In Central Utah and Western Colorado, finding late instar larvae on princes plume (Stanleya pinnata) around June isn't too difficult because of the strip patterns the larvae create on this and other host mustards.
