The Mountain Laurel Spectacular continues apace, and most folks I talk to agree that this Kalmia latifolia floral display is one of the best, if not the best, in recent memory. The Tiger Swallowtail butterflies certainly would concur, and their daily appearance at the Laurel fueling station brings up an interesting observation. While the Spicebush Swallowtails have been thick on the four-petaled blossoms of the Dame's Rocket mustards in front of the Laurels, those dark butterflies seem to avoid K. latifolia flowers. The Tigers, on the other hand, go easily and often to both kinds of blossoms, and, if anything, I think they probably enjoy the Laurels more than they do the Rockets. I haven't found any corroboration in the scientific literature for what I'm seeing as a preference, and, because I don't keep exactly meticulous records, I can't rule out the possibility that I'm just seeing things—that is, every time I look, I see Tigers in the Laurels and Spicebushes in the Rockets... but I don't look all that often, so my observations don't rise from qualitative to quantitative. So be it. Whatever I'm seeing, the vision is just beautiful. Maybe that's enough.
