Species Account

Sutton & Beaumont, 1989: There have been several more reports of this species since the last list (YNU, 1970). Whether these were spurred by the comment 'there are surprisingly few records', or whether there has been a genuine increase, is difficult to ascertain. However it probably occurs wherever gorse or broom is established and the moth has probably been overlooked in the past (SMJ pers. comm.).

2012 (CHF): There appears to have been a decline in recent years. Most of the latest records have been from coastal areas.
