Morley’s Final Catalogue: Not listed as a separate species.
Recent Status: Rarely recorded in Suffolk.
Life Style: A single brooded species flying May to July and coming to light. Where this species is separated from E. scutulana in literature then the larvae are stated as feeding on stem and root of Centaurea nigra. They hibernate and pupate in the larval habitation.
Identification: It should be noted that the Moths and Butterflies of Great Britain and Ireland Volume 5 treats this moth as a variant of E. scutulana. E. scutulana males have more extensive white areas than those of E. cirsiana but females can be very similar. There are slight differences in the genitalia that must be used for records of E. cirsiana females. More Info
