About Tortricodes alternella (Denis & Schiffermüller), 1775
Tortricodes alternella (Denis & Schiffermüller), 1775 is a moth species belonging to the family Tortricidae. It is present across most of Europe, with the exception of most of the Balkan Peninsula. This species has a wingspan of 19 to 23 millimeters, and is a slender moth. Its forewings are fairly narrow, and range in color from grey to brown, with a darker cross-band; occasionally the entire outer section of the forewings is darker. The hindwings are pale brown with darker veins. It resembles the male of Exapate congelatella, but Tortricodes alternella flies in spring rather than autumn. Adult moths are on wing from February to April. The larvae feed on a variety of trees and shrubs, including species from the Quercus and Carpinus genera. They spin the leaves of their host plant together, and feed inside this structure.
