Temperature Distributions on Butterfly Wings

Caption

Temperature distributions on the forewing of three species of Eumaeini butterflies illuminated by sunlight, showing that despite the wings' wide variation in visible coloration and pattern, the temperature of the scent patches, pads, and wing veins that contain living cells is always lower than that of the remaining "non-living" parts of the wings.
