Amazing World of Insect-Wing Color Discovered
Until now, the wing colors of many flies and wasps were dismissed as random iridescence. But they may be as distinctive and marvelous as the much-studied, much-celebrated wings of butterflies and beetles. ... Generations of biologists seem to have missed this partly because they didn’t look for it, and partly because the colors are most evident against a dark background. Against a white background, they’re invisible — which is exactly how most entomologists study transparent wings.
