Flower for the Day Field Aster 10-25-19

I have three different kinds of aster. In the front yard I have ones  with vivid purple flowers.

                       

In the wildflower garden the asters were much taller  and slightly more pale.

In a field circle the asters are medium in height and even paler.

 

                    

The butterflies flock to the field circle asters that are out in the open. There are still many small

yellow, white, and orange butterflies darting around even in late October.

Can you name this butterfly (above and below)? I think they are the same one.
