As I was wandering about Occoquan Bay National Wildlife Refuge earlier this week, I was struck by the large number of Common Buckeye butterflies (Junonia coenia) that I observed. Not only were there a lot of them, many of them appeared to be in almost pristine condition, unlike the tattered survivors of other butterfly species that are hanging on this late in the season.
I decided to do a little research and learned from bugguide.net that Common Buckeyes have two to three broods throughout the year from May to October. I had suspected that was the case and that helps to explain the “fresh” condition of the butterflies that I observed. What was a little more surprising to learn was that, “Adults from the south’s first brood migrate north in late spring and summer to temporarily colonize most of the United States and parts of southern Canada.”
I don’t know if the Common Buckeye butterflies in my area will migrate south to avoid the freezing temperatures that will soon be upon us or if they will remain with us. In either case, I love to see these little butterflies and marvel at the way that their colors fit in with nature’s autumn color palette.
