Coordinator notes: The reason I have identified the angle-wing in your picture as Zephyr (a subspecies of Polygonia gracilis) and not the Satyr is because the two spots on the forewings (one touching the bottom of the grass blade and the other just diagonally above it) are small. These tend to be larger and about the same size on the Satyr Angle-wing while they are both small here as typical on male zephyrus. Also, the Satyr usually has a distinct border on the hindwing that contains any marginal spots within it. This is much more diffuse on the Zephyr as it appears to be in your photo, mostly obscured by the grass. Mike
