Distribution Notes:



Habitat: C. discolor occurs in open woodlands and closed forest, and I have once seen it, in northeastern Illinois, in wet-mesic sand prairie (but near an old fence row with some woody vegetation and a dead cottonwood nearby).

Natural History: In the above-mentioned prairie setting, C. discolor was nectaring at the glandular hairs on the petioles of Helianthus grosseserratus. Feeding habits are probably much like those of C. nearcticus. Alates of this species are probably reared in late summer and fall, but do not fly until the following May, but there are no collection data to verify this.
