Heliozela sericiella is a moth of the Heliozelidae family. It is found in most of Europe, except Spain, Slovenia and most of the Balkan Peninsula.
The wingspan is 6–8 mm. Adults are on wing in May and June in one generation per year.
The larvae feed on Quercus petraea, Quercus pubescens, Quercus robur and Quercus suber. Young larvae bore in the petiole, bark or a twig of their host plant. This causes the petiole to swell gall-like. When almost fully grown, it moves through the midrib into the blade, creating a small blotch. Finally, an oval excision is made, which the larvae uses to vacate the mine and drop to the ground. Here, pupation takes place. The pupa overwinters. Larvae can be found from June to July.
