Behavior
Adults are seen flying from July to November and the larvae overwinter and emerge in the spring. They can be seen flying in many areas including fields, gardens, waste areas. Adults are nocturnal and often come to lights. In more arid areas adults can be found nectaring and resting on composite flowers in the late afternoon. Females will oviposit in flower heads, particularly in the heads of Asteraceae.Reproduction
