Erynnis martialis, commonly known as the mottled duskywing, is a species of butterfly in the family Hesperiidae. It is found in most of the eastern United States and in southern Ontario, and southeastern Manitoba. [2] It is listed as a species of special concern and believed extirpated in the US state of Connecticut. [3]
The wingspan is 25–29 mm. There can be two generations from mid-May to late August. [4]
The larvae feed on wild lilacs including New Jersey tea ( Ceanothus americanus) and redroot ( Ceanothus herbaceus) in the buckthorn family ( Rhamnaceae). Adults feed on nectar from flowers of Bush houstonia, Gromwell, Verbena stricta and other plants. [5]
Main threats posed to mottled duskywing populations are habitat loss, fragmentation and invasive species control measures. [6] Urbanization, suburban sprawl, agriculture and logging have destroyed many oak savanna habitats that the mottled duskywing rely on. [7] The spraying of DDT and carbaryl to control the population of the invasive gypsy moth also pose a major threat to the success of the species. [7]
