Subject: Insect wing colors
A new identification approach For conservators who work with insect collections or may encounter insect wings used as decoration: Until now, the wing colors of many flies and wasps were dismissed as random iridescence. But they may be as distinctive as those of butterflies and beetles. Researchers found that surface variations in chitin filtered out the iridescence. Remaining colors proved to be stable, and were visible from almost any angle. They differed consistently between species and sex. The colors are most evident against a dark background. Against a white background, which has been the standard procedure for studying insect wings, they are invisible. http://www.wired.com/wiredscience/2011/01/insect-wing-color/ Lisa Mibach *** Conservation DistList Instance 24:34 Distributed: Thursday, January 13, 2011 Message Id: cdl-24-34-003 ***Received on Wednesday, 5 January, 2011
