Gynnidomorpha alismana
Water-plantain Conch

(Ragonot, 1883)930 / 49.108

Morley’s Final Catalogue: Recorded from only Benacre, before 1890 (Crutwell).

Recent Status: Present in Suffolk at suitable wetland sites.

Life Style: A single brooded species that flies in the evening and comes to light during June, July and August. The larvae feed in a flowering stem of Alisma plantago-aquatica. They mine downwards in the stem and hibernate fully fed in a cocoon in the stem where they pupate.

Identification: Gynnidomorpha species have a darker central band, a pre-tornal patch, a pre-apical patch extending towards the termen and a slight band on the base of the dorsum that may reach the costa. The markings in the terminal third of the wing usually show a reticulate appearance. All have a very small patch of blackish scales inside the apex of the folds on the wing that run from the apex, centre of termen and tornus. This in common with some Phalonidia, Cochylimorpha and Phtheochroa species.
G. alismana is the largest of the British Gynnidomorpha. There is a prominent suffusion of blackish scales one third of the way along the central band from the dorsum. This species will also show a darker patch centrally before the termen. More Info
