Distribution and Abundance: Very local.

Primary Habitat: Grassland.

Flight Period: Single brooded in June and July.    

Observations: In the autumn of 2004 a small number of larvae of this species were swept from yarrow growing on the high lying rough grassland at the Northamptonshire Wildlife Trust Reserve of Barford Meadows. The caterpillars were reared through and moths were released on the Reserve in June and July 2005. This is a nationally spreading species and has almost certainly colonised other suitable sites in the county.

First Record: 2004, Ward.
