Lecithoceridae

Overview

The presence of dense secondary setae in the larva, sets the family apart from other Gelechioidea except Scythrididae, with which family it shares the presence of series of long, obliquely arranged setae beneath the fore wing and above the hind wing. The moths rest with head directed downwards and antennae held porrect. Most species occur in the Oriental and Australian regions, being mainly tropical and subtropical. Crocanthes (25 spp.) contains bright yellow, orange or pink species with dorsally spined abdomen. The males of some species, such as C . prasinopis , have segments 2 and 3 of the labial palps fused to form a long, weak, partly coiled segment. Lecithocera (65 spp.) includes dark species which shelter amongst the leaf litter. L . micromela from the south-east is common in dry, grassy places. [Gozma'ny 1978.]
