Morley’s Final Catalogue: Distinctly local; among Ballota nigra. Ipswich (Garrett); several imagines in Bramford marshes on hemlock in July 1894-9 (Mly); Orford in July 1902 (Gibbs); Aldeburgh (Hele) and one taken there (Ctw).
Recent Status: Recorded in Suffolk with a geographically restricted distribution.
Life Style: A single brooded day flying species found during June, July and early August. The larvae feed on Ballota nigra. They pupate in the larval habitation
Identification: Forewings are brassy, green basally and bronze purple towards the apex. There is a broad purplish black band at around two fifth. Antennae are dark basally and silvery white apically, longer for the male than female. Male head is black, ferruginous for the female. N. minimella is similar but the dark band is relatively narrower and although generally smaller the size ranges overlap. Where N. minimella is suspected owing to the presence of Succisa or Scabiosa then a genitalia dissection is required for identification of that species. The larvae initially feed on the seeds and then on lower and dead leaves from a mobile case. The case is oval, flattened, bivalve, constructed from silk, sand and pieces of dead leaves. It has a constriction. More Info
