There’s a lot going on in the backyard. Lots of blossoms and bees, and some butterflies. This area in particular is the scene of a lot of activity (click to view larger image).
I’m seeing numerous azures (Celastrina spp.), especially around the Virginia sweetspire (Itea virginica). These very small butterflies remind me of light-blue flying snowflakes. However, when they land they often close their wings and the blue color of their upper wings is hidden.
The Eastern tiger swallowtail butterfly (Papilio glaucus) is quite different in size and color. I was delighted to see this one on phlox. It was in pristine condition and I’m guessing it had only recently emerged from its chrysalis.
