Eucosma hohenwartiana
Bright Bell

([Denis & Schiffermüller], 1775)1200 / 49.266

Morley’s Final Catalogue: In profusion wherever it occurs, but we have few records. Ipswich in 1900 (Pyett); Bramford marshes, and always abundant at Monks Soham light in July and August, Slaughden (Mly); Hemley and Covehithe (Wir), Aldeburgh (Ctw), Sotterley (Gd), Beccles (Crf). Swilland, Kersey and Euston in 1933-4 (Whit).

Recent Status: The species found across Suffolk but it is a three species group. E. hohenwartiana is the commonest of the species.

Life Style: The moth is single brooded flying from May till August and coming to light. The larvae feed in the flower and seed heads of Centaurea nigra. They hibernate in a cocoon on the ground where they pupate.

Identification: This is one of three species of the E. hohenwartiana group. The males have a costal fold. The species can be separated on the larval foodplant by rearing through. The adult moths can be separated on size and the female genitalia. They cannot be separated on the male genitalia.
E. hohenwartiana is the commonest of the group and covers the entire size range. The species group distinction from some other Eucosma species along with the separation of the females in the group is shown by the genitalia dissection. More Info
