White Witch Moth (Thysania agrippina)

White witch moth of the Erebidae family was described for the first time in 1776 by a Dutch merchant named Peter Cramer. It has a wide and extensive range from South America’s Uruguay up to Mexico, extending to North America, up to Texas. The white witch moth gives tough competition to several other moths when it comes to size because of its large wingspan, though the Hercules moth and Atlas moth has surpassed it.
