Fruit beetle grub (Pachnoda sp.) These are another great worm to use as a treat for larger species such as Bearded Dragons, tegus and larger chameleon species. A good incentive for stocking these, in addition to the nutritional variety, is that they’re getting considerably more popular than the more ubiquitous Wax Worm given their fantastic price tag. The proliferation of Bearded Dragons & Monitor Lizards in the trade is probably the main reason why Pachnoda Grubs are fast gaining in popularity. It probably makes sense to consider these as an item you would routinely keep and feed your reptiles.
