context_page_description: Ypsolopha ustella, the variable ypsolopha moth, is a moth of the family Ypsolophidae. It is found in most of Europe and is also present in North America.
  The wingspan is 15–20 mm. It is a variable species with numerous colour forms. Adults are on wing from mid-July to April in western Europe, but can be on wing nearly year round depending on the location. The species overwinters as an adult.
  The larvae feed on the upperside of the leaves of Quercus species. They live under a slight web. Pupation takes place in a whitish boat-shaped cocoon on a leaf, trunk, or amongst leaf-litter on the ground.
