Common in Garrett and Allegany Counties especially at higher elevations.
The Appalachian Tiger Swallowtail is a recently described species that lives only in the Appalachian Mountains. This butterfly is much larger and paler than the Eastern Tiger Swallowtail. Although not easily distinguished from the Eastern Tiger Swallowtail while on the wing, in the hand look for the connected yellow bar on the ventral forewing. This is a diagnostic identification feature. There are also greatly reduced blue markings on the hindwing.
This butterfly has been observed at Swallow Falls State Park, in Garrett County (Maryland DNR: Swallow Falls).
Host plant is unknown although caterpillars of Appalachian Swallowtails have been known to feed on Black Cherry (Bugguide).
There are 35 records in the project database.
