Eastern Pygmy-Blues are Alabama’s smallest butterflies.  EPB’s flutter only inches above low-growing plants, often oblivious to observers.  They are tiny, but tough, adapting to harsh coastal and salt marsh conditions.

Eastern Pygmy-Blue caterpillars are highly camouflaged, looking exactly like part of their segmented host plants.  They most easily found by looking for ants that "tend" them in order to partake of the larvaes' sugary secretions.

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
