Northern broken-dash, Dun skipper, and little glassywing are called “the three witches” because their dark wings make it difficult to tell “which one is which.”
Northern broken-dash (Wallengrenia egeremet) is a small, dark, nondescript, grass skipper. It occurs in the United States and southern Canada east of the Rocky Mountains. It is most common in the northeast from Maine to Michigan south to Massachusetts and Ohio. It is uncommon but sometimes locally abundant throughout its range, including in Minnesota. Adults are found from late June to mid-August in open places near wooded or shrubby areas, including fields, pastures, meadows, woodland edges, gardens, and roadsides. They drink nectar from white, pink, and purple flowers, including alfalfa, red clover, dogbane, New Jersey tea, milkweed, and blazing star. Larva feed on the leaves of panic grasses.
The upper side of both wings is dark brown with pale markings and a brownish fringe. On the male the leading edge of the forewing is pale. The group of specialized scent scales (stigma) on the male forewing is black and is interrupted in the middle, like a “broken dash”. This is the feature that gives the species its common name.
