Goliath worms are known as the Carolina sphinx moth as adults and when they they are in their larval form, as the tobacco hornworm and the goliath worm.
They are very closely related to and often confused with the tomato hornworm. Both species feed off foliage of various plants of the family Solanaceae.
Lets take a look at their nutritional data and find out more.
In particular, their acidic, calcium, phosphorus, water, protein, fat, sugar, and fibre content is of most interest when it comes to bearded dragons.
Another thing of importance is the calcium:phosphorus ratio as for every part phosphorus, there needs to be another part calcium if not more. From 1:1 to 2:1 is ideal as far as bearded dragons are concerned.
Calcium: 46.4mg/100g or 464ppm

What makes them good is that they are low in fat and have high calcium content. But they also have no chitin which is their exoskeleton.
The reason this good is that chitin can often cause impaction in a bearded dragon which is where food blocks their intestinal trac. This can cause a lot of problems and ultimately in some cases, death.
Goliath worms are therefore a good feeder food for bearded dragons and can be purchased from many good pet stores and specialist stores online.
