Autumn Painted Lady Migration in Central Iowa

A southward Painted Lady migration has been underway in central Iowa for at least the past three days. After a summer with none observed here, a few appeared in late August into mid-September, and then recently, larger numbers arrived after September 21. Although most have been spotted nectaring, several have been seen flying southward after the passage of a cool front on September 24. As of today, September 26, winds continue blowing from northerly directions, carrying Painted Ladies southward at heights of from 5 to 10 meters/15 to 30 feet.
