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
Confined to a few localities in southern Britain.
Found at Gwithian (Tomlin, 1909).
Habitat & Ecology
Believed to be primarily associated with Lesser Dandelion Taraxacum laevigatum where it grows in sandy grasslands but there are no reliable records for Taraxacum laevigatum in Cornwall (C. French, pers comm .), so it must be using a related plant here. Larvae probably develop in the capitula or upper stems. The adult is flightless.
Coarsening and scrubbing over of dune grassland.
