Genus:Blastobasis
Species:adustella
Authority:Walsingham, 1894

Common in gardens, hedgerows and yew woodland throughout much of the British Isles. Like all Blastobasis sp., a naturalised species which has become well established, but as a native of Madeira, how it reached Britain remains a mystery (MBGBI Vol 4 part 1). In Hampshire and on the Isle of Wight widespread and common. Wingspan 13-19 mm. The adult, which is variable but generally easy to recognise, comes freely to light. The larva feeds on fallen leaves, fresh and decaying vegetable matter, refuse and detritus; there are a few records from Hampshire, from spinnings on flowerheads and in fruits collected in the field.
