The white tongues on P7,6, and 5 (subterminal band) bother me. I just do not think a GBBG would have this feature. The difference in color on the wings, brownish wash, black/gray is confusing, obviously molting. Missing P6 on left wing. Subterminal band ( or partial) on P5 another feature I do not think GBBG possesses. Add in the orangy/pink legs...?????I think this is hybrid of sorts.
