鈥淭hey are Painted Ladies (Vanessa cardui) and not Viceroys or Monarchs. There are a few compounding reasons we are seeing so many Painted ladies this week:

  1. They migrate south in the fall in search of warmer weather so we are seeing many of those migrants on their journey south.
  2. They migrate quite high in the sky but the recent warm weather has encouraged them to come down to the ground and forage for nectar.
  3. They were quite successful in breeding this year, so we are seeing much larger populations.
  4. It is interesting to note that we are experiencing an El Ni帽o year which has resulted in a wetter spring and an extended summer.鈥聽鈥擵inko Culjak Mathieu
