Anarsia lineatella Zeller, 1839 Species

Last modified: Jan. 5, 2024, 10:55 a.m.


In the past it was assumed that it was only one species, but since the publication of Keld Gregersen and Ole Karsholt in Nota Lepidopterologica 40(1):65–85, Taxonomic confusion around the Peach Twig Borer, Anarsia lineatella Zeller, 1839, with description of a new species (Lepidoptera, Gelechiidae) , we know that there are 2 species involved.
The first confirmed observation after 1980 is of a caterpillar found in a peach, origin from Spain, and bought in a supermarket in Zemst (VB) on 30.vi.2023.
