Anarsia innoxiella Gregersen & Karsholt, 2017 Species
Last modified: Jan. 5, 2024, 10:50 a.m.
This species is first described in 2017. 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.
This 'new' species is still rare but distributed throughout Belgium.
As far as we could ascertain, the first confirmed observation for Belgium was in 2011 in LI.
