Recent Status: Locally common at wetland sites with Eupatorium Hemp Agrimony.

Life Style: The moth is double brooded. The moth comes to light and can be found during the summer..

Identification: Suffolk’s smallest plume moth is usually pale but can be a light brown colour. It has a dot at the cleft and an elongate one on the costa, other spots may be present in well-marked specimens. The termen and dorsum scale fringes of the first lobe of the forewing are both brown. There is usually a yellow tinge around the saddle (posterior of thorax-anterior of abdomen).
The larvae feed by mining into the stem and often producing a stem gall. They overwinter as a fully grown larva in the stem of the foodplant. They can be found in Eupatoruim by searching for entrance holes showing frass.
