Wings black above, spotted with white near the tips of the first pair, on which is also an orange-red band across the middle; hind wings with a marginal orange-red band, Fig. on which is a row of black dots, the two nearest to the hind angle having a pale blue centre. Expands from 2J to 3 inches. The Atalanta butterfly was probably introduced into America from Europe with the common nettle, which it in- habits. It deposits its eggs in May upon the youngest and smallest leaves of this plant, being cautious to drop only one upon a single leaf. The young caterpillar is guarded against injury from the poisonous prickles of the leaf by the numerous branching spines with which it is covered, and which, being longer than the prickles, prevent its body from coming in contact with the latter. The head is cov- ered with a tough shell, which sufficiently protects this part, while its strong and horny jaws are adapted for cutting and chewing the leaves and their prickles with impunity. As soon as the caterpillar is hatched, it spins a little web to cover itself, securing the threads all around to the edges of the leaf, so as to bend upwards the sides and form a kind of trough, in which it remains concealed. One end of the cavity is open, and through this the caterpillar thrusts.
