Submitted by: EvSherr
Specimen type: Photograph
Observation notes: 100 or more of these butterflies were resting on a short stretch of this gravel road for several days. Observed in previous Septembers also. The owner of the house next to the road sprinkles the gravel to keep the dust down, so perhaps the butterflies were attracted to the moisture. Warm (80 oF) clear day.
