Wijuti, Witchety, or Witchetty Grubs,
Goat Moths, Carpenter Moths, Wood Moths,
The COSSIDAE include many species with large Caterpillars and moths up to 17 cms in wingspan. Many of the Caterpillars have an unpleasant smell: hence their name Goat Moths. Most of the Caterpillars are borers in trees, hence their other names. The Witchetty (Wijuti) Grub is generally the Caterpillar of Endoxyla leucomochla.
The Caterpillars may take up to three years to mature, and pupate within their tunnels.
The moths have long narrow wings, like those of Hawk moths, and are mostly grey.
The 87 named Australian members of COSSIDAE are:
