The name Ya Mie Die (, Yǎ Miè Dié), literally Small Elegant Butterfly, is derived from Japanese yamete (), meaning stop, a reference to the rape genre in Japanese pornography and the common Chinese stereotypes of the Japanese as being erotomanic, misogynous and perverted. It was supposedly a type of butterfly discovered on 1 January 2009 at the Qinghai-Tibetan Plateau, and that legends state that there was once a Japanese girl who turned into these butterflies after harsh pressures during a romantic relationship. The original article states that these butterflies are able to change colour, and are luminescent, naturally emitting light from their wings. This is due to the cold temperatures and low oxygen environment these butterflies live in. There are an estimated 14,000 butterflies living throughout the world, and thus are considered to be precious and highly uncommon.
