She looks like an olive greywing spangle, possibly clearflight pied - hard to tell without seeing the back of her. Does she have a "bald spot" on the back of her head (patch without any barring)? The greywing mutation dilutes the body colour somewhat, and also lightens the wing markings.
She's a beauty! Lucky you!
