Number: 500

Uncountable numbers. Mostly feeding on goldenrod. I and one other person tagged 94 in 1.5h. I have never seen so many before.

If I had to give a best estimate on the number I saw when we were out it would be closer to 500. It felt like each swing of my net would get 1-2 butterflies. Most of them were feeding on goldenrod.
