The wingspan is 11–14 mm.[2] Adults are on wing from June to July and again from August to September in two generations per year. The adult overwinters and reappears the following spring.[3]

The larvae feed on Inula conyza. They mine the leaves of their host plant. The mine has the form a long and narrow corridor that starts at the midrib or at the leaf base. Later, it becomes a large, full depth blotch nearly without any frass. A larva may vacate the mine and restart elsewhere. A second mine has no initial corridor. Pupation takes place outside of the mine.[4] Larvae can be found from April to May and again from June to July.
