Are butterworms good for my pet?

Yes and no. They are a good source of protein and vitamins, which means that they are not just "empty calories" for exotic pets. However they are very high in fat, so they should not be fed regularly.

Can butterworms be used as a staple feeder?

No. Due to their extremely high fat content, butterworms should be offered as occasional treats for omnivorous and insectivorous pets. Feeding butterworms and other fatty foods too often can lead to excessive weight gain and associated health complaints such as fatty liver disease.

How do I take care of my butterworms?

Your butterworms will arrive in a plastic cup with sawdust substrate. From this point they are extremely easy to keep. Simply stick the container in the door of your fridge until you need them for feeding your pet. Take the cup out of the fridge for an hour or so to let the worms warm up before feeding.

What do butterworms eat?

Butterworms exclusively eat the leaves of the Tebo tree. This can make them difficult to breed when Tebo leaves get scarce due to factors such as forest fires. Fortunately you don't have to feed them once they've arrived on your doorstep. Keeping them cool keeps them in a dormant state where they don't need to eat or drink.

How big do butterworms get?

Butterworms can grow up to 2-3 cm long. 

How long do butterworms last?

When kept properly cool, butterworms can last up to three months.

Why are butterworms sometimes hard to find?

The food that butterworms eat, Tebo tree leaves, gets scarce in the event of natural disasters and poor weather. Without Tebo leaves, you can't raise butterworms. So the availability of butterworms highly fluctuates depending on the availability of Tebo leaves.
