Adult butterflies nectar on a variety of native and cultivated flowering plants.
Spicebush Swallowtails can be found in a variety of habitats such as woodlands, fields, roadsides, yards and parks.
After mating females lay eggs individually on the underside of host plant leaves. Caterpillars remain on the host plant until pupation.
In the northern part of the range there are 2 flights per year from April-October and in the southern areas there are several generations per year.
The caterpillars of the Spicebush Swallowtails have eyespots on their backs making them resemble a snake head. They also make shelters out of host plant leaves where they can hide when not eating.
