Morley’s Final Catalogue: Also a good deal neglected, doubtless frequent. Orford in July 1902 (Gbs); at Monks Soham light in July 1912-35, and quite common at a lantern beside Fritton Lake in August 1934.
Recent Status: This species is not so common as the similar Endothenia quadrimaculana.
Life Style: This is a single brooded species flying from June to September. The larvae feed in the stem and roots of Stachys palustris and also S. sylvatica and Mentha arvense. The larvae hibernate and pupate in a cocoon in or around the larval habitation.
Identification: A brown species with darker brown markings showing a triangular mark centrally pointing to the dorsum that has an angle of 90 degrees or slightly less. It is similar to the larger E. quadrimaculana where the triangular mark shows an obtuse angle.
