Davey, P., 2009: A moorland species in northern Britain, a fenland species in East Anglia, and found in river valley habitat in Hampshire, the larva feeding in the inner stems of rushes (Juncus spp.), club-rush (Scirpus spp.) and cotton grass (Eriophorum spp.); the foodplant in Hamshire is unknown. In Dorset, a strong colony was detected about seventy-five years ago at Morden Bog where cotton grass may have hosted the species. The last record was from 1937. An old record from the nineteenth century from Poole (E Blanchard) has not been validated. "When Blanchard was collecting round Poole, he had Luscombe Bottom, Heavenly Bottom and Haymoor Bottom wholly undrained and exactly as Morden Bog was before the Forestry Commission interfered with it. I, personally, have seen all three before drainage had rendered them unsuitable for marsh loving insects, and feel sure that Blanchard could, and did, get the insect." (W Parkinson Curtis ms). The Dorset form is of a much softer, pinker colouration than its northern counterpart. Recent visits to the site have failed to locate a colony, but the fen habitat at the site with some cotton grass has remained largely intact despite intensive coniferisation right up to the edge of the bog and around its perimeter from the 1960s. There is a chance that the species survives there still and further searches for the species during August and early September are recommended. Morden Bog, two at light in September 1927 (H Andrewes), at light on 2 August 1933, seven between 15 August 1937 and 3 September 1937 (A Russell).
