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 popularity as pests. However, the large caterpillars of species that do not smell badly are often edible.
Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of ...
A large bright rufous triangular patch is found over the whole outer area of the forewings. A black sub-apical speck visible. Cilia rufous. Hindwings reddish brown suffusion with rufous outer margin. The caterpillar is 35–40 mm in length. It is a multivoltine moth species, where organism having more than two broods or generations per year. [5]
The other caterpillars in this size range are almost universally Sphingidae, which are seldom hairy and tend to have diagonal stripes on their sides. Many Sphingidae caterpillars bear a single curved horn on their hind end. These are actually not dangerous, but large, hairy caterpillars should generally not be touched except by experts.
Sphingid caterpillars are medium to large in size, with stout bodies. They have five pairs of prolegs. [5] Usually, their bodies lack any hairs or tubercules, but most species have a "horn" at the posterior end, [2] which may be reduced to a button, or absent, in the final instar. [5]

[13]: 644 Caterpillars of many taxa that have sequestered toxic chemicals from host plants or have sharp urticating hair or spines, display aposematic colouration and markings. [66] Caterpillars undergo ecdysis and have a number of larval instars, usually five but varying between species. The new cuticle is soft and allows the increase in size ...
