Morley’s Final Catalogue: A local species, feeding in seed-heads of carline thistles. Taken at Orford by Gibbs in 1903 (Trans, i, 36).
Recent Status: A rare species in Britain and restricted to the Suffolk coast.
Life Style: A single brooded species that flies in June, July and August. The larvae feed on the seeds of Carlina vulgaris inside the seed-head with little external evidence. They hibernate fully fed and pupate in the seed-head.
Identification: This is the smallest of the Metzneria species but it overlaps the size of, and is similar to, M. aprilella. Both lack the two dark spots of M. lappella and M. metzneriella and both are predominantly a bright sandy brown colour. They are keyed in the Moths and Butterflies of Great Britain and Ireland by the M. aestivella third labial palp segment not being thickened with appressed scales. More Info
