Butterflies - Mid Wales

A rapid flyer. One of the top butterflies to spot in woodland areas. This species emerges in July and August. The silver-washed can be identified by its double row of spots along the edges of the wings. Males, such as this one above, can be distinguished by the black scent-scale lines on the forewing. These contain scales laden with pheromones which are dropped over the female during the courtship flight.
