Do you know what a goliath beetle likes to eat? Well I am going to tell you what it eats. Goliath beetles eat fruit but they can chew fruit and they can also drink tree sap. There claws dig on the tree to get the sap. The baby eats rotting plants from the soil. The baby might also eat small beetles and larva. They might also eat adult bugs. Goliath beetles also like to eat dead plants and animal poo. That's all to no about what they eat. Sometimes they like to gather and eat in the ground and that's where they live.
