It's ridiculously cool today, about 10 degrees this morning, and wet, but a few days ago in the warm, the swallowtail butterflies appeared, as they seem to every year. Apparently swallowtails don't migrate, and the pupae can overwinter, so once it warms up in the spring, the butterfly can emerge.
They fly back and forth, up and down, meandering from flower to flower, fluttering in the breeze. They seemed to really enjoy the lilac blooms, going back to those repeatedly. One also sat still on a 'wooden heron' we have, enabling me to get some good pictures.
