Cossidae, the cossid millers or carpenter millers, make up a family of mostly large miller moths.

Like the latter, its relationships to other Cossidae are not determined with certainty.

Mormogystia is a genus of moths belonging to the family Cossidae.

Aethalopteryx obsolete is a moth in the Cossidae family.

Phragmataecia minor is a species of moth of the Cossidae family.

The Cossidae are today usually divided into six subfamilies, but numerous genera still await placement.

They are insectivore, feeding primarily on beetle larve and Cossidae caterpillars.

Mormogystia is distinguished from all other Cossidae genera by having large silvery areas on the forewing.

Large silvery areas on the forewing forming fasciae make this the only Cossidae genus to have such a high contrast pattern.

Species of Lissonota have long ovipositors able to reach deep wood-boring Lepidoptera such as Cossidae.

Volume 2 (Cossidae to Heliodinidae)

The Poplar Carpenterworm (Acossus centerensis) is a moth of the Cossidae family.

Ratardinae is a small subfamily of moths formerly placed in its own family Ratardidae and related to (and often included within) Cossidae.

The Red Coffee Borer (Zeuzera coffeae) is a moth of the Cossidae family.

The whitchety grub is sometimes inappropriately included but these insects are larvae of moths, principally in the family Cossidae and to some extent Hepialidae.

The Sesbania Stem Borer (Azygophleps scalaris) is a moth in the Cossidae family.

The Australian Goat Moth (Zyganisus caliginosus) is a moth of the Cossidae family.

Psychidae, Thyrididae, Metarbelidae, Aegeriidae, Cossidae, Hepialidae.

The Quince Borer, Sad Goat or Apple-trunk Borer (Coryphodema tristis) is a moth of the Cossidae family.

Many species from other families such as Arctiidae, Nepticulidae, Cosmopterygidae, Tortricidae, Olethreutidae, Noctuidae, Cossidae and Sphingidae are aquatic or semi-aquatic.

These large Microlepidoptera[1] are restricted to Andean South America, from where they were described originally in 1989 in the family Cossidae by their discoverer Patricia Gentili.

Some unrelated millers were included in the Cossidae in error too, such as the genus Holcoceroides which are more primitive Ditrysia, or the Andesianidae which are even more ancient Heteroneura.

Many are twig, bark or leaf mimics, and Cossidae often have some sort of large marking at the tip of the forewing uppersides, conspicuous in flight but resembling a broken-off twig when the animals are resting.

The first is considered a distinct family of the Cossoidea today recognizable by their abdominal tympanal organs which the Cossidae lack, whereas the other two are usually kept in the Cossidae as subfamilies.

Colonies of these ants inhabit a majority of pine trees in the area, living in chambers in the outer bark of living trees that have been abandoned by bark-mining caterpillars, usually of the family Cossidae.
