Morley’s Final Catalogue: By no means so frequent as the last kind; confined to small patches of plantago in coast salterns at Hemley, Hollesley Orford in 1932-5 (Whit.), Aldeburgh and Southwold in 1891-7 (Ctw Barrett); Lowestoft salt-marshes (Bd).
Recent Status: A common species on Suffolk salt-marshes currently.
Life Style: A single or sometimes double brooded species that comes to light from May to August. The larvae feed on Aster tripolium. They start on the flowers, or buds and bore down into the root stock where autumn larvae may overwinter fully fed. They may pupate in this location or elsewhere on the salt-marsh.
Identification: The moth is an ochreous brown with an oblique brownish stria from the dorsum at one third that fades before reaching the costa. The stria lacks the dark central mark of Gynnidomorpha vectisana that can also be found on the salt-marshes. There may be a small tornal spot and slight strigulation over the wing.
