Butterworms – Consider This..


Butterworms (Chilecomadia moorei) are the Chilean Moth in the larval stage, they are a great source of calcium and protein. Not suitable as a staple feeder due to the fat content, they are an incredible occasional treat for any pet because of their captivating scent and colour! Measuring on average between 2-3cm long butterworms are also called Tebo worms or Trevo worms.

Food and Water

In the wild, the butterworm eats the leaves from the Tebo Tree. Upon receiving your order of butteworms you merely place them in the fridge, the hibernated state slows their metabolic process means they have got no requirement for any food or water. They are going to survive like this within your fridge for as much as 4 months!!


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


Butterworms are irradiated before being shipped from Chile. This prevents the worms from pupating in to a moth, as many countries begin to see the Chilean moth as a pest, Chilean laws prevent them from leaving the country having the ability to pupate to Moth. So butterworms can not be cultured in your own home.

Disease & Sickness

The key point to concentrate on will be the dampness of the substrate the worms are stored in. You want to avoid mould growing inside the container. Ensure that you change any damp bedding inside their container and you ought to do not have problems.

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

Butterworms, like mealworms, are used as food for insectivore pets, including geckos and other reptiles, as their scent and bright color help attract the better stubborn eaters. Also, they are called tebo worms or trevo worms, and they are rich in fat and calcium. These are hard to breed in captivity, and most are imported directly from Chile. They are usually irradiated to kill bacteria preventing pupation because the moth is an invasive species.

Butterworms, like all the popular “worms” available as feeders, are in fact the larval stage of the insect. Inside the case of butterworms the adult stage will be the Chilean Moth, Chilecomadia moorei; they are also called the Trevo- and Tebro- worm (and even a couple of 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 out of Chile, C. moorei larvae are irradiated to kill parasites, and, it is speculated, to stop them from pupating. I have seen websites contradicting this, and claiming that the 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 reasons unknown C. moorei can’t pupate outside Chile, the actual fact keeps them a lucrative export for that country, frustrates hobbyists like myself, and prevents C. moorei from becoming one of many premier feeder insects available.
