NOMADS AMONG THE BUTTERFLIES ) National Geographic Society Painting by Hashime Murayama FAR-FLYING WANDERERS, WINGS FLAPPING VIGOROUSLY, HEAD FOR THE OPEN SEA Thousands upon thousands of butterflies make up this golden horde, seen from a steamer deck near La Guaira, Venezuela. Seldom do they rise more than three feet above the surface of the Caribbean. Where they go, and why they leave home, no one knows. The yellow "Traveling Butterfly" (Plate II, fig. 3) comprises nearly half the group; numerous also is the orange Phoebisargante (Plate II, fig. 5). Stragglers include Phoebis philea (Plate II, fig. 4) and Phoebis cypris (Plate II, fig. 6). About 250 species of butterflies are known to migrate. Most of them take only one-way passages from their birth place; a few make return flights.
