Cossidae
family of lepidopteran insects
The Cossidae, the cossid millers or carpenter millers, make up a family of mostly large miller moths. This family contains over 110 genera with almost 700 known species, and many more species await description. Carpenter millers are Lepidoptera found worldwide, They are nocturnal, except for the Southeast Asian subfamily Ratardinae.
This family includes many species with large caterpillars and moths with a wingspan from 9–24 cm (3+1⁄2–9+1⁄2 in). These moths are mostly grey; some have long, narrow wings and resemble hawkmoths (Sphingidae) which are more advanced macrolepidoptera, however. 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.
Caterpillars are smooth with a few hairs. Most cossid caterpillars are tree borers, in some species taking up to three years to mature. The caterpillars pupate within their tunnels; they often have an unpleasant smell, hence another colloquial name is goat moths.
The family includes the carpenterworm (Prionoxystus robiniae) and the goat moth (Cossus cossus) which have gained notoriety as pests.

Why this record matters
“Cossidae” is worth following because a concise public description often conceals a longer documentary argument. Here, Cossidae, family and lepidopteran provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q838122. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
