Observations: My own field records show that I have seen the moth in the county in eight of the last ten years to 2009. It was particularly common on 12 September 1987 at Geddington Chase with fifteen recorded in four actinic light traps left overnight. There is a record of a caterpillar being taken on blackthorn in May 1958 at Salcey Forest, but I have found it more readily on hawthorn sunning itself in late spring.
