About Ancylis myrtillana (Treitschke, 1830)
Ancylis myrtillana is a species of moth in the family Tortricidae. It was first described by Treitschke in 1830. It is found across most of Europe and the Palearctic realm, and has also been recorded in North America. Its preferred habitat is moorland. The wingspan of adult moths ranges from 12 to 16 mm. The forewings are ochreous or pale brownish, and are sometimes marked with whitish striations. The posterior section of the costa has dark fuscous spots, and there is a rather dark fuscous, irregularly triangular dorsal blotch that extends from the base to beyond the middle of the wing; the area surrounding this blotch is sometimes entirely whitish. The central fascia is ochreous-brownish, with a wedge-shaped posterior projection that points upwards from below its middle, and bears one or two black dashes in its center. The hindwings are grey. A full species description is provided by Julius von Kennel. Adults are active on the wing from May to July, with one generation produced per year. The larvae feed on the leaves of Vaccinium myrtillus, Vaccinium vitis-idaea, and Vaccinium uliginosum. They feed inside a sheltered pod formed by spinning two leaves together. This species overwinters as a final instar larva inside a cocoon built in plant litter.
