LEPIDOPTERA 515
(3) THE HAJRSTREAKS. These butterflies are distinguished by one or two
thin tails on each of the hind wings. They are usually dark in color. The
males have a tuft of hair-like scales or beard on the front. The great purple
hairstreak, Atlides halesus (Cramer), expanse 30-38 mm., is iridescent purple,
blue, or greenish above and with two pairs of tails. The larvee feed on mistletoe,
and the species ranges from tropical North America far north into the temperate
areas. The bean lycrenid, Strymon melinus (Hilbner), expanse 25-30 mm.,
is gray; the larvre feed on legumes and other unrelated plants, as well as fruits,
throughout North America. The banded elfin, IncisaUa niphon (Hbn.),
breeds on pine east of the Rocky Mountains.
