Bordered Gothic Sideridis reticulata
A declining species, now restricted to a few scattered localities in the south-east of England, though formerly somewhat more widespread in the south. Its preferred habitats are chalk downland, waste ground and sand-dunes or sea-cliffs, where the adults fly in June and July. Image: Michał Brzeziński (iNaturalist).
