Western Swallowtail

Western Swallowtail butterflies seem to be really abundant this August.  In my front yard, and everywhere I see flowers in front yards when I walk to town.  I wonder if they're taking advantage of the absence of competitors.  This one by Quincy Natural Foods was so engaged in sipping nectar it et me get fairy close.  With a normal, 50mm lens, I got within a couple of feet and was able to take a dozen photos without scaring it off.  Click on it and you might see a hole in one of its wings.  Reminded me of bad old days when I used to shoot them with my BB gun.
