One generation. Mid September to late April. Overwinters as an adult, being active in mild weather. Larvae are present April to June, hiding by day and feeding at night. It builds a cocoon undereground from where it pupates about three months later.
Larval foodplants
Omnivorous. Larvae feed on leaves of oaks, elms, Hawthorn, Blackthorn and Hazel at first, but after it has grown, wit will prey on other moth larvae.
Unmistakeable with the small kidney mark and its two satellites in each bottom corner, but variable in the colour of them.
