Morley’s Final Catalogue: One of our commonest Tortricina. Mildenhall, Bramford and Blaxhall in May; sitting on Heracleum flower on 24 July 1908, and very frequent in fly-trap at Monks Soham. Attacks yarrow and oxeye-daisy.
Recent Status: A rare species in Suffolk possibly under-recorded.
Life Style: A single brooded species flying from May to July and coming to light. The larvae feed on the rootstock and then on the surface of the roots of Leucanthemum and Achillea. They pupate in a cocoon on the ground.
Identification: The male of this species does not have a costal fold. The ground colour is grey or fuscous with ochre tipped scales. The ochre may sometimes be extensive obscuring other markings but be absent, or greatly reduced, in the basal third. The pale costal strigulae subtend plumbeous striae. These may join the dorsal mark and may continue to the tornus. There are black spots on the termen and there may be black scales centrally in the terminal half of the wing. The cilia are grey, white and silver. Genitalia dissection is required to confirm identification for a record. More Info
