Eastern Tiger Swallowtail

Eastern Tiger Swallowtail, Papilio glaucus
The Eastern Tiger Swallowtail, while an easily distinguished eastern butterfly, has a vast number of variations especially between genders. One particular dark phase of the female has a resemblance to the Pipevine Swallowtail though it lacks the poisonous quality. Depending on location, these butterflies may be seen flying anywhere between February and November, from Ontario down to Texas and no farther west than Colorado. Sources of nectar for this species include thistle, black-eyed susan, spicebush, honeysuckle, elm, and ironweed, and host plants include willow, elm, cherry, and poplar to name a few.
