Luke Brown, a butterfly expert at London's Museum of Natural History, said only 0.01% of butterflies have experienced this problem. Mr. Luke has built the first house for butterflies since he was 7 years old and there are more than 300,000 butterflies hatching here, but this is the third time the hermaphrodite has occurred.

According to BBC, the wings of the butterfly split into a dark side of the " male " gender and a more colorful side of the " female " gender . Not only the wing but its body is also divided into two, the genitals are also in "half - half" condition, even its beard has a different length. The cause of this particular bisexual case is due to the unsuccessful separation of sex chromosomes during fertilization.

This bisexual butterfly belongs to the species Papilio memnon, a butterfly of Asian origin and is in the " middle age " after three and a half weeks of coming out of cocoons. After the end of a month-long life, the butterfly will be displayed at London's Museum of Natural History, so the people have little chance to admire this butterfly while it is alive.

Bisexual phenomenon is not only found in butterflies but also in crabs, lobsters, spiders and chickens. Other animals can also occur in this case but it is difficult to detect because the males and females are quite similar.
