Orange-barred Sulphurs became established in Florida in the late 1920’s and have become common residents.  They fly year-round in south Florida and spread north each year, but they are uncommon in the Panhandle. Although these sulphurs are less migratory than Cloudless Sulphurs, there are numerous records throughout the eastern United States.  Alabama’s documented sighting occurred on December 2, 2013 when both Patsy Russo and Ben Garmon photographed a winter-form female on Dauphin Island.   

Distribution and Abundance

A dot on the county map indicates that there is at least one documented record of the species within that county. In some cases, a species may be common throughout the county, in others it may be found in only a specific habitat. The High Count information shows the highest numbers recorded for this species as well as when and where they occurred.

The sightings bar graphs depict the timing of flight(s) within each of three geographic regions. Place your cursor on a bar within the graph to see the number of individuals recorded during that period.

The abundance calendar displays the total number of individuals recorded within each week of the month. Both the graphs and the calendar are on based data collection that began in 2000.

The records analyzed here are only a beginning. As more data is collected, these maps and graphs will paint a more accurate picture of distribution and abundance in Alabama. Submit your sightings to
