Area Sighting
Seasonal Flight DataAs a rare stray to north Texas records indicate that it does not show up here until summer and fall.
General NotesThoas Swallowtails are found from southern Texas southward to Brazil, Cuba and Jamaica, with various subspecies throughout its range. The Thoas Swallowtail (subspecies autocles) is a rare stray into the north Texas area, but just how rare is not clear. Because of its remarkable resemblance to the Giant Swallowtail, it is possible that it is more common than records indicate. Closer examination of Giant Swallowtails, both in the field and in collections, is needed. At any rate, it is an uncommon visitor to the Dallas/Ft. Worth area.
