Large Salmon Arab Butterfly

Large Salmon Arab Butterfly photographed by Jeffrey Zablow in Binyamina, Israel

Our 2nd post of a male Madais Faust. Here we view the ventral (below-the-wing) surface. Our earlier view of a Large Salmon Arab examines the dorsal (upper) wing features.

An example of the Pieridae species, the Madais Faust is related to the white butterflies and the yellow butterflies that are so well known around the globe. This of course is an Israeli Pieridae. North American Pierids include the abundant Cabbage White butterflies as well as the common Orange Sulphur butterflies.

Reference guides explain that the yellow wing color is caused by high concentrations of stored uric acid.  Uric acid is the nitrogenous compound produced when proteins are metabolized. This stored uric acid reflects ultraviolet light. How that UV radiation is reflected impacts the courtship and reproduction success of each individual. Neat, huh?
