Morley’s Final Catalogue: Noticed only at Southwold in 1888 (Ctw), though doubtless not rare among oxeye-daisies.
Recent Status: A rare species in Suffolk.
Life Style: A single brooded species flying in July and August and coming to light. The larvae feed in stems of Leucanthemum species. It is not clear which stage passes the winter. They pupate in a cocoon either in the larval habitation or in the ground.
Identification: The easiest of Dichrorampha species for identification. The forewings are very dark brown or black and marked with white. There are prominent plumbeous striae from the costal strigulae and black spots on the termen. The cilia show a white band. The males have a costal fold to one third. The larvae cause a slight swelling in the stem of Leucanthemum resulting in a cessation of the growth of the plant. The larvae then feed upwards into the flower. Abnormally spindly side shoots of the plant may occur.
