Stunned and delighted to find a Cassius Blue nectaring in my favorite local dogbane patch. I saw a small blue fluttering over the flowers and assumed it was Cupido or Celastrina, but when it landed, I could see the bold ventral pattern and smaller size. The creature was very jittery, startled into the air frequently by the many wasps and bees and by my own movements. On the wing, it flashed clear, pale blue. I managed a couple of poor photos with my phone before it disappeared. I pulled out my DSLR and hunted the area for an hour or so but couldn’t find it again.
