Ubiquitous

The spread of this species in our area is extremely well-documented. It was confined to the Thames Estuary until the end of the nineteenth century. The first Middlesex record was in 1890 at Harefield; the first in Hertfordshire was at Berkhamsted in 1945. The twentieth century saw scattered records across much of the area, but up to the end of 1999 it appears that all reports relate to single adult moths. Post-2000, however, many traps began recording between 2 and 5 individuals per night, with occasional higher numbers. The Least Carpet is now a firmly established resident throughout both counties.
