This is interesting, it’s a rare gynandromorph butterfly that has recently hatched at the Natural History Museum. The butterfly is half male and female and has both sex organs fused together. The insect is almost black on the male side with the female side being paler with specks of blue. red and tortoiseshell. It is possible for insects for born gynandromorphs when the sex chromosomes fail to separate when the fertilised egg divides. Only one in every ten thousand butterflies is a gynandromorph. The butterfly is expected to have a normal life span of around a month, although it is infertile so will not produce eggs. It will become part of the museums collection when it dies.
