It is found from Europe to Russia. The wingspan is 12-15 mm. Adults are on wing from July to August. The larvae burrows into a twig of a Populus or Salix species and later occupies a leaf bud. A moth is an insect closely related to the butterfly, both being of the order Lepidoptera. Moths form the majority of this order; there are thought to be 150,000 to 250,000 different species of moth (about ten times the number of species of butterfly), with thousands of species yet to be described.
