Summary

Galacticidae is an enigmatic family of moths in the order Lepidoptera. Recognized recently, they are moderate-sized, exhibiting structural similarities with other lepidopteran families and known for species like the mimosa webworm. Their classification is still under evaluation, particularly regarding relationships in the Apoditrysia natural group.

Physical Characteristics

Galacticidae moths have a wingspan of 8–17 mm. Some possess spined abdominal segments in their pupal stage.

Identification Tips

The genus Homadaula resembles yponomeutid genera such as Prays and Atemelia, as well as certain 'small ermine' moths.

Habitat

Galacticidae are found in a variety of habitats in the Old World, including Africa, Madagascar, Asia, Australia, and New Caledonia.

Distribution

Distribution spans the Old World: from Africa and Madagascar to Asia, Australia, and New Caledonia.

Economic Impact

The mimosa webworm (Homadaula anisocentra) is considered a pest of ornamental plants and has been introduced to eastern North America.

Evolution

Galacticidae was previously included in several lepidopteran superfamilies but is now placed in its own superfamily, Galaticoidea, at the base of the Apoditrysia group. Their phylogenetic relationships, particularly using DNA data, need further exploration.

Misconceptions

There has been discussion about whether their removal from the Yponomeutoidea is justified due to structural similarities and similar larval behavior.
