Great Purple Hairstreak on Clethra, REB 2013 July 27, Pocomoke City MD. This hairstreak feeds exclusively on mistletoe, so its range is restricted to places where mistletoe grows — in the East, mostly along the coast.

Giant Swallowtail is one of the largest butterflies in the U.S. In recent years it has expanded its range from its normal southern distribution up into Canada. In the South, where they caterpillars feed on citrus and sometimes cause substantial damage, the caterpillars are sometimes known as “orange dogs.”

Many butterflies are very similar but share the same habitat by using different resources. This picture compares Banded Hairstreak (right) with Striped Hairstreak (left) on a dogbane flower in College Park, MD taken 2013 June 17 by Beth Johnson.
Hayhurst’s Scallopwing takes advantage of a common garden weed, lambs’ quarters, as a caterpillar host. It will adapt readily to suburban life. Photo REB 2012 July 15, US National Arboretum.
Frosted Elfin is a butterfly whose range and abundance are very restricted. First it flies only in early spring for two or three weeks, when its food plant, wild lupine, is in bloom. The eggs are laid in the flower buds, as in this picture, which the caterpillar eats. Lupine is rare, growing only in very special habitats, mostly on the Coastal Plain in the mid-Atlantic.

Mulberry Wing skippers are also threatened in much of their range. They live in wet meadows, typically beaver flooded meadows, with abundant sedges. These habitats are often drained for agriculture or for suburban development; there are only a handful of known locations left in Maryland for this once-widespread species.

Crimson Patch is common in Mexico and usually enters the U.S. only in the Southwest and Texas. This one was photographed by REB in August 2013 at the National Butterfly Center.
