A family of primitive monotrysian moths in the order Lepidoptera, Heliozelidae are small, metallic day-flying moths with shiny smooth heads. In Europe the small adult moths (genera Antispila and Heliozela) are seldom noticed as they fly quite early in the Spring. The larvae are leaf miners and the vacated leaf mines are distinctive because the larva leaves a large hole at the end.
