What type of insect is a white witch?
"Thysania agrippina" is a species of moth in the family Erebidae. The most commonly accepted common name is "white witch". "Thysania agrippina" is of interest as a competitor for title of "largest insect." This may be true by the measure of wingspan—a Brazilian specimen with a wingspan of almost 30 cm (12 in) appears to hold the record. The Atlas moth and Hercules moth, however, have greater wing areas. The white witch occurs from Uruguay to Mexico, and appears as a stray as far north as Texas in the U.S.
