Davey, P., 2009: A local species found in large reedbeds in southern and eastern England, the carnivorous larva feeding on vegetable and animal matter within dead stems of common reed (Phragmites australis) that have been broken or tunnelled by Twin-spotted Wainscot2370, Brown-veined Wainscot2371 and Fen Wainscot2377 moths (it apparently cannot enter an unopened stem). It will also eat the membranous lining of the stems. In Dorset, the moth is frequent within all the larger coastal reedbeds on the Fleet, at Radipole and Lodmoor, and around Poole Harbour and Christchurch Harbour, so all those occupied by the other Wainscot species mentioned. No examples have been found in the extensive reedbed at Morden Bog. There are many records from localities some distance from coastal reedbed, and occasional short to medium range dispersal is suspected for these. The well-marked forms ab. bipunctata, where the reniform and orbicular stigmata are black and circular, and ab. wismariensis, where black median longitudinal suffusion extends from the base of the wing to the termen, have both been recorded in Dorset. The brood cycle is rather obscure and additional records are needed to clarify an apparent multivoltine pattern.
