Status:

Dainty Sulphur (Nathalis iole), the smallest species of sulphur in North America, was only recently recorded in Maryland in 2012, when a significant irruption event led to numerous sightings across several states. This tiny butterfly is found primarily in the deep south, but irrupts northwards into the Great Plains and portions of the West annually, where it does not overwinter successfully. It flies low in a wide range of open habitats (Butterflies of Maryland: A Biological Summary and Checklist by Lynn Davidson & Richard Smith; Brock & Kaufman 2003; BAMONA site.

Relationships:

Uses a variety of Asteraceae as larval food plants.

There are 24 records in the project database.

A Dainty Sulphur in Montgomery Co., Maryland (8/3/2012). A first state record found by Dave Czaplak! Dave first glimpsed one individual on 7/29 but returned on 8/3 and found at least six. Even smaller than our irruptive Little Yellows, Dainty Sulphurs are the smallest sulphur species in the U.S. They are present in much of the Great Plains and Southwest, as well as the Southeast.
