Butterworm

The butterworm is the larval form and is commonly used as fishing bait in South America.

[2] Butterworms, like mealworms, are used as food for insectivore pets, such as geckos and other reptiles, as their scent and bright color help attract the more stubborn eaters.

They are difficult to breed in captivity, and most are imported directly from Chile.

They are usually irradiated to kill bacteria and prevent pupation as the moth is an invasive species.
