There are only five species of Trogossitidae in Britain, but they have a diverse ecology.  One, Lophocateres pusillus (Klug), is a stored product pest found only in artificial conditions.  Thymalus limbatus (Fabricius) and Ostoma ferrugineum (L.) are found beneath bark, the former frequently and the latter rarely, in Caledonian forest remnants in association with the dyer’s polypore fungus Phaeolus schweinitzii (Fr.) Pat.  Of the remaining species, Tenebroides mauritanicus (L.) is a pest of cereals and Nemozoma elongatum (L.) is a rare predator of Acrantus vittatus (Fabricius).
