Austrochilus

Austrochilus is a genus of moths in the family Hepialidae. These moths are native to Australia and are known for their relatively large size and their caterpillar's wood-boring habits. The genus was first described by Charles Oberthür in 1907.

The larvae of Austrochilus moths are significant pests of various timber species. They bore into the roots and lower stems of living trees, often causing considerable damage and leading to the decline or death of the host plant. This wood-boring behavior is characteristic of many Hepialidae moths.

Adult Austrochilus moths are typically nocturnal and are attracted to lights. Their wingspans can vary, but they are generally considered to be robust moths. The exact distribution and host plant preferences can differ among the species within the genus. Further research is ongoing to understand the full ecological role and economic impact of Austrochilus moths in their native habitats.
