Appalachian Brown

Appalachian browns are found in wooded wetlands, shrub swamp, and along forest edges. They tend to prefer the edges of woodlands as opposed to open marshes or meadows; red maple swamps containing sedges are the most ideal habitat.

• This butterfly is fairly well-dispersed throughout the eastern United States, but there are northern and southern populations which are univoltine and bivoltine, respectively.
• Appalachian browns are not migratory but are not considered sedentary either. They do tend to wander short distances beyond their local habitat areas.
• Until 1970, this butterfly was incorrectly thought to be the same species as eyed brown (Satyrodes eurydice). Appalachian brown, eyed brown, and northern pearly-eye (Enodia anthedon) often live in adjacent habitats and can be easily misidentified.

Appalachian brown is  globally listed as apparently secure . Illinois  lists the species as one of Greatest Conservation Need . The species is critically imperiled in Vermont and New Hampshire, and only listed as secure in Connecticut.

There are no correlations for Appalachian browns between phenology an abundance.

Many of these sites show large variation in the abundance (activity index), which is typical of insects. Phenology is also quite variable across the observation period, which for most sites is ~1990-2019.
