Eastern Black Swallowtail Butterfly
| Additional Butterfly Information Swallowtail Butterfly Pictures Types of Butterflies |
The species is fairly wide spread throughout the Eastern United States. However, the population also extends through areas of the Midwest and Southwest with sufficient larval plants, typically those in the parsley and carrot family.
Because parsley species grow throughout the spring and summer months, Black Swallowtails can be found from Spring through early Autumn in their range.
In some areas, they overlap with the black form of the Eastern Tiger Swallowtail, so a close inspection of the wing pattern is necessary for identification.
