Wingspan 19 to 22 mm. A rather plain brownish species.

As the name suggests, this is a species generally found in and around plantations of Larch.

It flies during May and June, when it can be attracted to light.

The small stripy caterpillar feeds on the needles of larch, and is well-camouflaged. The species overwinters in the pupal state.

Distributed widely throughout the British Isles where Larch is present. In a recent survey to determine the status of all macro moths in Britain this species was classified as common.

Occasional in Leicestershire and Rutland. L&R Moth Group status = C (very scarce resident or rare migrant).
