Nationally scarce (Na) in urban areas and on old buildings in southern England. First recorded in South Hampshire in 2013, and found on the Hampshire/Surrey border in North Hampshire in 2023. While occasionally reported, records are often unsupported by sufficient evidence to allow acceptance; it is probably under-recorded as very similar to B. dryadella and often only separable by dissection of the genitalia, however shape of fascia is straight or slightly inwards-bent in B. dryadella, but slightly outwards-bent and rarely straight in B. basaltinella (MBGBI Vol 4 part 2). Larva feeds on various mosses, living within a silken tube or tent.
