Butterworms – Things To Consider..


Butterworms (Chilecomadia moorei) are the Chilean Moth in the larval stage, they are a good source of calcium and protein. Not suitable as being a staple feeder because of the fat content, they are an excellent occasional treat for any pet because of the captivating scent and colour! Measuring typically between 2-3cm in length butterworms are also known as Tebo worms or Trevo worms.

Food and Water

Within the wild, the butterworm eats the leaves from the Tebo Tree. Upon receiving your order of butteworms you just put them in the fridge, the hibernated state slows their metabolic process means they may have no need for any food or water. They are going to survive like this in your fridge for up to 4 months!!


Keep your butterworms in a plastic container, with an organic substrate, like wheat bran for example. Place the container inside the refrigerator, but make certain they will remain dry. Check the worms after about one hour. When they are webbing the substrate together, leave them. If they are not, change the substrate right away. Damp substrate will lead to mould forming. They can survive between 1 to 4 months in a hibernated state.


Butterworms are irradiated before being shipped from Chile. This prevents the worms from pupating into a moth, as many countries see the Chilean moth being a pest, Chilean laws prevent them from leaving the nation having the ability to pupate to Moth. So butterworms should not be cultured at home.

Disease & Sickness

The primary point to concentrate on is definitely the dampness from the substrate the worms are kept in. You need to avoid mould growing within the container. Make sure that you change any damp bedding in their container and you should do not have problems.

he Chilean moth (Chilecomadia moorei) is really a moth from the family Cossidae. The butterworm is definitely the larval form and is also widely used as fishing bait in South America.

Butterworms, like mealworms, are used as food for insectivore pets, such as geckos along with other reptiles, as his or her scent and bright color help attract the better stubborn eaters. They are also called tebo worms or trevo worms, and are rich in fat and calcium. They may be difficult to breed in captivity, and many are imported directly from Chile. These are usually irradiated to kill bacteria preventing pupation as the moth is definitely an invasive species.

Butterworms, like all the popular “worms” available as feeders, are in reality the larval stage of your insect. Within the case of butterworms the adult stage will be the Chilean Moth, Chilecomadia moorei; also, they are called the Trevo- and Tebro- worm (and even several cases of Tebo- and Trebo), and therefore are like silkworms in that they feed exclusively on a single species of tree, the Trevo/Tebro/Trebo/Tebo, Dasyphyllum diacanthoides.

C. moorei are exclusively found in Chile, and they are considered a possibly invasive species. When shipped away from Chile, C. moorei larvae are irradiated to kill parasites, and, it is speculated, to prevent them from pupating. We have seen websites contradicting this, and claiming that this reason C. moorei larvae don’t pupate in captivity is because they mjruif a nearly 6 year larval stage, but it has result from only some small, un-notable sources. For whatever reason C. moorei can’t pupate outside of Chile, the simple fact keeps them a lucrative export for the country, frustrates hobbyists like myself, and prevents C. moorei from becoming one of many premier feeder insects available.
