description White witch Overview
The white witch, Thysania agrippina, is a large moth of the family Erebidae found in the Neotropics, including Central and South America. Its broad, pale wings carry fine darker lines that create a bark-like pattern. Exceptional specimens can exceed twenty-eight centimeters across, placing it among the moths known for the greatest wingspans. That measurement describes the spread of the wings, rather than body size or total wing area.
Its appeal extends beyond sheer dimensions. The muted pattern contrasts with the brighter coloration of many other conspicuously large moths, and helps explain why an impressive insect can still be difficult to notice against a suitable background. Entomologists and collectors interested in tropical moth diversity find it a distinctive subject. For general natural-history readers, it provides a useful example of how size and camouflage can coexist, and why different measurements produce different claims about the largest insects.
