While looking for the Blue Grosbeaks seen here recently, I noticed quite a few butterflies and dragonflies. The very large, dark butterfly threw me - it was quite iridescent blue on the hingwings above, but didn't seem to have tails, or any yellow spots. It was either a huge Red-spotted Purple, or a dark E. Tiger female with no tails. Oh, and I saw the male Blue Grosbeak!
