As promised... photos of the butterflies. I first posted about them yesterday, but for some reason Blogger didn't like my post and the whole thing disappeared! My apologies to those of you who discovered an empty blog post.
More importantly, I discovered the hard way that my photography skills are lacking. Try as I might, I never got one single good picture of the full impact of this winged invasion. There are butterflies everywhere, particularly on my mimosa trees. It appears as if the trees are alive with fluttering movement. It is breathtakingly beautiful. Alas, I have no photo that captures the scene.
However, I promised. So here they are.
From my web research, I believe they're probably Spicebush Swallowtails. They are enjoying all of our flowers, but seem especially attracted to the mimosas.
