Aethes cnicana
Thistle Conch

(Westwood, 1854)945 / 49.127

Morley’s Final Catalogue: Found among thistles at Benacre and Kessingland (Ctw) Gorleston in May 1934 (D); Thetford (Williams).

Recent Status: Found across Suffolk with a preference for wetland locations

Life Style: Single brooded in mid-summer. Flies in the evening and night and comes to light during May, June and July. The larvae feed on Cirsium thistle seeds and later in the stem where it hibernates.

Identification: A glossy pale ochre with a dark dorsal blotch at around a third reaching two thirds to the costa. There is a less clearly defined costal mark to match and three less clear blotches from pre-tornus across to the costa. The two costal marks may extend a suffusion towards the dorsum. The costa is darkened at the base. The species is very similar to A. rubigana which flies a little later but the flight periods overlap. There is a difference in the shape of the dorsal blotches between the two species and the three blotches beyond are more clearly defined in A. rubigana.
