Heliozelidae

Overview

The moths, which often have metallic scales, fly in sunshine and rest on flowers. The larvae are leaf- and petiole-miners in trees and shrubs, finally cutting out flat, oval cases from the mine, which either drop to the ground or are attached on the host or elsewhere before pupation. Hoplophanes (20 spp.), with wingspan up to 16 mm, contains the largest heliozelids. Heliozela , with many Australian species, often mines young terminal leaves of Eucalyptus . Antispila , with few species in eastern Australia, mines leaves of Cissus .
