Yellow Butterflies (Coliadinae)

The yellow butterflies seen in fields, forests and backyards around North America also go by the name sulphur butterflies (Coliadinae). With approximately two dozen native species, divided into ten separate genera, sulphurs show some diversity within the larger butterfly family, Pieridae.

Almost half of the Coliadinae species, approximately one dozen, belong to one genus, Colias. Most species grow to an above average size, having a two to three inch average wing span.
