Recent Status: A common species in Suffolk especially on the coast.

Life Style: A double brooded species that flies from May to September. The larvae feed in the stem and roots of Carduus nutans, Cirsium palustre and C. vulgare. They hibernate and pupate in the larval habitation.

Identification: The males of this species are easily recognised from the large areas of white on the wing. The females are less easily separated from E. cirsiana and records for individual females where males are not recorded must be supported by genitalia dissection if they do not show the extensive white areas.
