A University of Pennsylvania scientist co-authored a research paper that sheds new light on the previously dismissed wing colors of many insects, reports Gizmodo.
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."You hold the wing up against the light, so you can see the veins," said study co-author Daniel Janzen, an evolutionary ecologist at the University of Pennsylvania. "If you're looking through a microscope, you try to get a clear view behind the wing. It's the antithesis of getting wing color."Original source: Gizmodo
