Mottled Duskywings are known from only a few locations in Alabama. According to NatureServe (a network of biodiversity scientists), Mottled Duskywings are rare, declining, or eradicated throughout their eastern range. These skippers are dependent on habitats that support their only known host plant, New Jersey Tea, a small shrub in the Buckthorn family. While this plant is widespread in Alabama, the butterflies do not appear to be. Some lepidopterists believe that multiple patches of the host plant are required within an area that covers at least 250 acres.

Mottleds emerge a little later than other spring-flying duskywings. They are double-brooded, although the first brood may be larger than the second. Males are often seen perched, with wings widespread, on limbs and twigs growing close to the ground. They also sip moisture and minerals from damp soil. Although these skippers obtain nectar from flowers, they also make use of carrion and other non-floral food sources.

The Mottled Duskywing is found throughout much of the eastern United States but is more common in the western part of its range.

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 albutterflyatlas@gmail.com.

Common New Jersey Tea (Ceanothus americanus) is the only known host throughout Mottled Dusywing's range. It has also been documented in Alabama.
