Two-tailed Swallowtail

An early Two-tailed Swallowtail fluttered across my New Mexican brother's lawn while we visited last March. Not always common, this butterfly is found from British Columbia east to central Nebraska and south through Mexico. Adults take nectar from a variety of weeds, including thistles and milkweeds. This species is similar to the Eastern Tiger Swallowtail but has thinner and fewer black stripes and each wing has two tails. It is that state butterfly of Arizona.
