White Morph Monarch Butterfly by Abhisaek MD

A white Monarch, named nivosus by Lepidopterists, is grayish white in all areas of the wings that are normally orange (Vane-Wright 1993). Several authors (Stimson and Meyers, 1984; Vane-Wright 1993) have assumed that the white form results from the inability of the butterfly to synthesize the normal orange pigment, but this hypothesis has never been tested. The white Monarchs appear to be normal in all other respects giving rise to many questions. Why is this form so rare? Is nivosus selectively eaten by predators? Does it have difficulty finding mates? Is the genetic basis for this form the same in all populations? These, and many other questions, need to be answered.
