I was on my patio and happened to see quite a few butterflies fluttering around our trees. I was surprised to see them roosting. I had never witnessed this before. The butterflies appeared between 6:35 - 7:15 pm on September 29, 2015. I estimate there to be about 50 butterflies. We have 2 large trees in our backyard, one is an oak tree and we do not know the species of the other tree. The butterflies seemed to roost on the west side of the trees which placed it closest to our house. I estimate the wind to be about 7 mph, but I am unsure of the direction. The overnight low would have been about 65 degrees. There is a large alfalfa field about 20 miles north of Altus.
Today (9/30) at Altus AFB, I noticed about 36 butterflies of various sizes heading south between 8:30-8:45 am.

This evening (9/30) I noticed about 15 butterflies flying through our yard, but only saw 2 roosting in a tree between 6:30 - 7:00. Wind was ESE 5mph. Rain is in the forecast for this evening. Overnight low is supposed to be 61 degrees.
