873 Blastobasis adustella
Walsingham, 1894Wingspan 15-20 mm.
An adventitious species, this moth was introduced into Britain, and is now well established throughout. Formerly known as B. lignea, this in fact was a misidentification of 873a B. vittata, for which lignea is now a junior synonym.
Occurring mainly in August and into September, and nocturnal, it is a common visitor to the light-trap in many areas.
The larvae feed on a variety of foodstuffs, including decaying vegetable matter.
