Thoas Swallowtail (Papilio thoas autocles)
Collected by: Arthur A. Brown, Kiest Park, Dallas, TX July 2, 1942.
Currently in the permanent collection of the Dallas Museum of Natural History.
|Caterpillar Hostplants||Major host plants are members of the Piperaceae family, which are not found in North Central Texas. Scott shows other hosts include those used by Giant Swallowtails such as Prickly Ash (Zanthoxylum), Hop Ash (Ptelea), Lemon (Citrus limon) and Rue (Ruta graveolens).|
|Seasonal Flight Data||As a rare stray to north Texas records indicate that it does not show up here until summer and fall.|
|General Notes||Thoas 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.|
