Species Account

Argus 52, 2006: This moth is currently going a major range expansion from its stronghold in the Thames Valley. In the recent Rothamsted report Least Carpet was top of the table of moths increasing in number. It will be interesting to see whether it continues to spread throughout Yorkshire.
VC61. Kilnsea, 5.7.2006 (BRS). NEW COUNTY RECORD.

Current status (CHF, 2011): NEW COUNTY RECORD - Spurn 2006 and 2008. This species was first recorded in London in 1831. A major range expansion to the north and west took place from the 1950s and in the Rothamsted data, the population increased by 41,000% between 1968 and 2002 making it the moth with the greatest population expansion. It was only a matter of time before one reached Yorkshire, and we are likely to see more in years to come.
