Rare Butterfly Is Half Male, Half Female

An unusual butterfly that is half male and half female recently caught the eyes of a volunteer at a butterfly exhibit at Drexel University in Philadelphia.

Chris Johnson, a retired chemical engineer from Swarthmore, Pennsylvania, was volunteering at the exhibit when he stumbled across the unusual sight.

Johnson noticed that the insect's two right wings were typical of the females of its species — they were larger, and brown with yellow and white spots. But its two left wings were smaller and darker, with splashes of green, blue and purple, a pattern characteristic of males.
