The vast majority of the Red Admirals you see will be migrants, though some do manage to hibernate through the winter nowadays.
There is no butterfly with which this can be mistaken.
Male and female are similar, though the male is slightly smaller. If you see a butterfly nectaring on flowers in the shade, it is almost always a Red Admiral. It will also feed on blackberries and rotting fruit.
