Mar 2005: I
now believe this is A. adippe based on the concave forewing outer
margin.
This is a powerful butterfly. It is usually seen
flying fast across open areas of grass and herbs. It is also found in
forest meadows but this is less usual. It resembles the High Brown and
Niobe Fritillaries, A. adippe and A. niobe. It is
(usually) readily
distinguishable by the notes given on adippe.
