What is "heliozelidae"

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.

The family is worldwide but the recently discovered genus Plesiozela from southern South America (which has five segments in the labial palps) may represent the sister group of living heliozelids (Karsholt and Kristensen, 2003).
