Larch Tortrix Zeiraphera griseana

(Hübner, [1799])


Wingspan c.16-22 mm.

The forewings of this species are lightly speckled with white, caused by white tips to many of the darker scales. This distinctive feature is described in the literature as 'farinose', likened to a dusting of flour.

Generally associated with larch (Larix) and other coniferous plantations, but also found in gardens and parks where these trees grow, the adults fly in July and are attracted to light. It is reasonably common in suitable habitats throughout much of Britain.

Feeding on conifers, but especially European larch (Larix decidua), the larva lives inside a tube-like spinning among the leaves.
