Eating my bagel at lunchtime today I looked out the window and I saw two large, beautiful butterflies. I ran to get my camera and reached the garden in time to see three butterflies seemingly dancing with each other, but they flitted away before I could take a photo.
So here’s the Berkeley puzzle. What might they have been? I looked at Art Shapiro’s Butterfly Site and I think I have two possibilities: either the Lorquin’s Admiral (left) or Chalcedon Checkerspot (right) . Can anyone knowledgeable suggest which it was likely to be? They were large and the coloration was something like the photos above. Guidance would be welcome.
