Also called Leopard Lilies, California Tiger Lilies are gracing us with their presence. Lilium pardalinum is their Latin name. They are native to California and southern Oregon. They grow near water, loving boggy conditions.
Here a Western Tiger Swallowtail Butterfly is feeding on a Tiger Lily. I saw one of these butterflies today, flitting through my garden.
In my original post I identified this butterfly as an Anise Swallowtail. Ron LeValley kindly gave me the correct identification and sent this link, which shows both butterflies, side-by-side: http://levalleyphoto.com/gallery/viewphoto.php?id=37 Thanks, Ron!
