General comments:

Probably ubiquitous

B. lacticolella did not reach Britain until 1946, when it was found in south-east London (Wakely, 1947). The first Hertfordshire record was not until 1987 when I found it in my garden light trap in Bishops Stortford, but it was probably established earlier, because that was my first full year in residence in the county and apart from Raymond Uffen, whose stalwart efforts have produced many new species for the county list, it appears that there were no other microlepidopterists in the county since the departure of Eric Bradford in the late 1960s. We were able to define the species as 'expected everywhere' by the year 2002, but in truth it had probably reached this abundance by about 2000.

In older books it is called Blastobasis decolorella, in error.
