This is a day-flying moth, unusually being on the wing in the early part of the year between March and April, preferring to fly in sunshine.
The greenish caterpillar feeds firstly on the catkins, and then on the leaves of birch.
Locally distributed in England, Wales and parts of Scotland. In a recent survey to determine the status of all macro moths in Britain this species was classified as local.
Fairly frequent but not common in Leicestershire and Rutland. L&R Moth Group status = B (scarce resident or restricted distribution or regular migrant).
