This individual was nectaring at Asters by the edge of the woods and was so placid that I was able to coax it onto my finger, where, as one can see in this photo, it probed for moisture and minerals with its proboscis. This same day and in this same location an Eastern Comma winter form was also nectaring at Asters.
