Chloroclysta siterata (Red-green Carpet) §3 male

ID: Variable in strength of median and basal fasciae and extent of reddish streaking or marbling. Females tend to be a darker richer green than males. Generally distinguishable from similar species by the reddish streaking; a short pale band distal to the costal end of the median fascia; blacker dorsal end of the median fascia; and grey hindwing. C.miata (Autumn Green Carpet) has a paler green ground colour, lacks the reddish streaking/marbling, the subbasal and median fasciae are more obviously edged white and the hindwing is whitish. Colostygia olivata (Beech-green Carpet) flies earlier (Jul-Aug), has a dull green ground colour. Like C.miata It lacks reddish streaking/marbling, has obvious white edging to the fasciae but it has a grey hindwing.
