Fomoria septembrella
Hypericum Pigmy

(Stainton, 1849)42 / 4.078

Morley’s Final Catalogue: Observed only in a gravel-pit on Southwold Common in September 1910 (Morley, Trans, i, 37).

Recent Status: There are a number of records for Suffolk.

Life Style: A multi-brooded species with the adult moths being found from May to September. The larvae mine leaves of Hypericum species. They pupate in the larval habitation inside a cocoon. They pass the winter as the pupal stage.

Identification: The adult moth is black and speckled paler. There is a white pre-tornal spot and the cilia and scape are white. The head tuft is orange. The moth can be identified by breeding out from a mine or by genitalia dissection.
The larva emerges from an ovum on the underside of a leaf and feed in a long narrow gallery that eventually leads to a blotch usually placed centrally in the leaf. More Info
