The Tiger Swallowtail butterflies are here, in force. They take their name from the long extensions on the tail of the wing, reminiscent of the wings of the swallows we see everywhere right now as well.
Since all these lovely flutterbys eat is nectar, they have been thick on the apple, cherry and lilac trees.
They only live a month or two before laying their eggs. There will be two generations up here in the North -- in the south, they can go one more for three. Tiger swallowtails overwinter in the larva or chrysalis stage, hatching in late May.
