Constant wave of butterflies heading Southwest. Wave has been steady for a least an hour
Observed between 8am to 10am+ I would like to add to the numbers as I would estimate a little higher maybe 200+.
Our home and rooftop deck is three stories high and most were at that level and above but when we left the house we noticed many at 10-15ft as well.
Winds were from the NE probably 10-15mph
We have a very bee and butterfly friendly rooftop garden but not many nectaring. Most were resting in a tree near us.
