- care required in the identification process, as confusion with similar species is likely - quality photographs required. ID pointers: The ground colour of the male wing is an orange-brown with a wavy cross-band running through the central area of the forewing. This band is usually a darker contrasting purple-brown. Can be very faded and most often is on migrants. The female is better marked being a deep rosewood-brown with a distinctive white ring shaped central forewing spot and faint whitish wavy cross-lines.
