Two-spotted Skipper (Euphyes bimacula)

Two-spotted Skipper (Euphyes bimacula)

One of the rarest butterflies in North Carolina, this distinctive skipper is known from only a few locations.

On 6/18/06 Ted Wilcox and I discovered a colony of them in a wetland in Alleghany Co., NC. We counted an amazing 16 this day -- a record high count for the species in the state. This is the first record from the North Carolina mountains -- an extension of the northern population, which occurs from the Virginia mountains northward.

They are found in wet areas with sedges (their host plant) - we saw three in a wet powerline cut through young second-growth forest, nectaring on Viburnum nudum.

The most distinctive thing about these dark brown butterflies is the white line along the body on the edge of the hindwing. "Two-spotted Skipper" is an exceptionally poor common name, derived from the specific epithet "bimacula", which means two-spotted. Females have two pale spots above, but so do a number of other skippers. A better name would be something like White-lined Skipper.

I discovered this one at an unexpected location along the Blue Ridge Parkway, near the crest of a ridge 100 yards or more from the nearest sedgey wetland.

On this female (same individual as above) you can see the two spots for which the skipper was named.

On June 10, 2007 I returned to the area to search for nearby sedge fields that might have Two-spotted Skippers. I hit the jackpot, finding 28 on National Park Service land (22 in one field alone), including the five pictured here.
