This moth appeared on our back porch yesterday and we have never seen anything that big before. The wings measure 5 1/2 inches from tip to tip. What type of moth is this?

Black Witch

Hi Angie,
This is a female Black Witch and your sighting is unusual because the Black Witch is a neotropical species that is found in Mexico, and does not breed in the U.S. except near the southern border.  For over 100 years, there has been documentation of the fall migration of Black Witches north, as far away as Canada, but the reason for these migrations is unclear as the moths will not survive the winter, cannot mate without their food plants, and do not return.
