“Start” of Butterfly Season!

I mentioned a northern species that emerges early up north, but aside from that, this week really seems to be the first big “push” of butterflies! I made this list of dates from the histograms on Wisconsin Butterflies. I went through every species, and picked its first seasonal “peak,” and then listed it by its approximate week of most likely occurrence. So, for late  in the 2nd week May (starting roughly May 12) into 3rd (May 19).
  • Henry’s elfin
  • Chryxus Arctic
  • columbine duskywing:Trails and roadsides, ravines, and steep wooded slopes where Wild Columbine grows.”
