General Description

By Nora Bryan

The Christina Sulphur can be found across Alberta. Look for it in woodlands, in open areas and along roadsides, especially in the mountains from June through August.

The outer two-thirds of the upper side of the forewing is orange and bright yellow at the base. There may be a brown band on the outer wing margin and there is a brown spot near the middle of the leading wing edge. The underside of the wing is olive-yellow and there is a silver spot ringed in brown in the middle of the hindwing.

The green caterpillars have lengthwise alternating dark and light stripes. It feeds on leguminous plants.

At one time this butterfly was considered to be a subspecies of the Queen Alexandra’s but has now been given full species status based on distribution, habitat preference and distinctive ultraviolet wing patterns.
