Zeiraphera griseana
Larch Tortrix

(Hübner, 1799)1166 / 49.257
=Zeiraphera diniana

Morley’s Final Catalogue: Discovered at Orford in July 1902, and at Felixstow the next year, by Gibbs (EMM. 1904, 80). Bentley Woods in 1933 (Mly).

Recent Status: A scarce species in Suffolk.

Life Style: A single brooded species flying from June to August. The larvae feed on Picea sitchensis, Larix decidua, Pinus species and Abies alba. They pupate in a cocoon on the ground.

Identification: This is the largest Zeiraphera species at 16 to 22 mm wing span (Z. isertana 14 to 19mm, Z. ratzebergiana 12 to 16 mm). It has relatively longer wings and the pale dorsal blotch extends over a greater proportion of the dorsum than in the other species. Male Zeiraphera do not have a costal fold. Z. griseana colour ranges from grey black to brown and their marking may be obscure but are consistent.
The larvae of Z. griseana feed on terminal shoots by spinning them together and feeding on the needles from the tip to the base. They move between shoot tips.
