The larvae feed on "Cerastium fontanum" and "Stellaria media". They mine the leaves of their host plant. The mine has the form of a short, inconspicuous corridor which is not lined with frass. The frass may be ejected out of the mine or is deposited in the mine as a broad pale orange central line. Older larvae live freely among spun leaves. Larvae can be found from April to May.
