Scientific name: Deltote uncula

May - July. Britain and Ireland. A small, olive-brown moth with a white hook-like mark on the forewing. Found in fens, marshes, boggy heathland and moorland.

The Silver Hook is named after the distinctive creamy white hook-like markings on the otherwise deep brown forewings. It is a smallish, slender moth with grey streaks along the leading and trailing edges of the wing which can have a pinkish tinge when freshly emerged. Although it can be seen flying by day and is easily disturbed from vegetation, it also flies at night.
