LIDWINA FIGURE-8 BUTTERFLY
UNDER THE GLASS
The butterfly or moth collector gets only a partial return on his efforts if he fails to examine his specimens under a medium power lens. The wings and body are covered with tiny scales, each a little jewel fastened to the wing by a slender stalk, side by side, in generally regular rows. Each row overlaps the row below—row upon row like shingles on a roof. Along the edges of the wings the scales are sometimes elongated to form a fringe. It is the scales that characterize the butterflies and moths as the scientific order Lepidoptera, a Greek word meaning scale-winged. It is also these scales that form the pattern and supply the color to the wings. Handle a butterfly with your fingers and the scales will be dislodged as a colored powder on your hands. The wings will then be left nearly colorless or only an opaque gray or brown membrane. On a few butterflies or moths, such as the Uraniidae, that shine with iridescent blues, purples and greens (opposite), there is little pigmental coloring. Instead, one sees the blue, purple and green light waves flashed from microscopic striations on the little scales that refract the light beam into its component color waves. Butterflies may be distinguished from moths by the knobbed tips of the antennae and the fact that they fly in the daytime. Moths have antennae that either taper to a slender tip or are feathery or fernlike in shape. Moths generally are night fliers, but a few fly in the daytime. These usually are more brightly colored than night moths and are frequently taken for their allies—the day-flying butterflies.
