Hall and Plant wrote in Ent Rec 134(2) April 2022, following Berggren et al, 2022 in ZooKeys 1085 that B. pinicolella should be split into two species, with B. confusella being new to science. The two can only be reliably identified by dissection.
B. pinicolella appears restricted to Norway Spruce, with confusella having a wider range of pabula, on various Pinus species and Larix. As such it can be expected that most, if not all, Hampshire and Isle of Wight records refer to the latter.
Given the above, there are at present no confirmed records of either species for our area. The mapped distribution refers to what for now must be considered to be pinicolella/confusella agg.
