| Authority: | (Hübner, [1799]) |
Local in woodland throughout much of the British Isles. In Hampshire very local and scarce in larch woodland, specimens sometimes wandering and turning up at light in unexpected places, but usually there are just two or three records per decade. Not recorded from the Isle of Wight to date. Wingspan 16-22 mm. Distinguished from Z. isertana by its larger size and the farinose coloration of the forewing, head, thorax, patagium and tegula [Bradley]. Larva feeds on European Larch, Scots Pine and Lodgepole Pine, living between needles spun together with silk, over-wintering as an egg.
