World Distribution: Eurasiatic; widespread across northern and central Europe to central Asia.

Irish Distribution: This species is recorded primarily from larch plantations and has a sporadic distribution across southern counties. It is likely to be more widespread than present records indicate especially in the west.

Ecology: A woodland species found in well established conifer plantations. Adults are attracted to light and appear in small numbers. Individuals can occasionally be found during the day by beating the lower branches of the foodplant. The larvae feed from the end of June until the beginning of August on Larch Larix decidua.

Key Identification Features:

• Dark patches and a sharp angulated median line
• White crest on thorax
