The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Widespread but very local in southern England, with probably more records from Cornwall than any English county.
Known from a scatter of localities in both vice counties, with recent records from near
Saltash, Tresco, The Lizard, and Clahar Bridge, Lizard. Also recorded at St. Columb Major in 2005 and near St. Mawgan, both by Ian Hoare (2005), near Gweek by John Owen and reported from Porthcothan (Shirt, 1987).
Habitat & Ecology
Feeds on Water Figwort Scrophularia auriculata and Balm-leaved Figwort Scrophularia scorodonia .
The Figworts are dependent on disturbance to create suitable germination grounds;
natural flood-scouring in the case of Water Figwort, and natural erosion through cliff
falls, wind-scouring etc. with Balm-leaved Figwort. Threats come from attempts to control natural erosion.
Allow natural riverine and coastal processes to continue uninterrupted.
