Mealworms vs Superworms for Bearded Dragons
Similar looking feeders with different sizes, shell content and risks. Which suits a juvenile, which suits an adult, and why neither is a staple.
The short version
Between these two, superworms are the more useful feeder for an adult because they carry more soft tissue relative to shell, though they are also fattier. Mealworms are smaller, which suits a juvenile on size grounds, but they are frequently criticised for a high proportion of hard exoskeleton relative to nutrition. Neither should be the staple. If you want a worm in the rotation, black soldier fly larvae beat both on calcium content. Size any feeder to the space between the dragon's eyes, whichever species it is.

Choose the Live Mealworms, 1000 Medium if…
Choose mealworms if you need a small feeder and cannot get better options, keeping them as an occasional item rather than a routine one. They store well in the fridge, which slows their development, and they need bringing back to room temperature before feeding. Dust them at the same schedule as anything else. Watch the size rule closely with juveniles, since it is easy to buy a grade that is too large without noticing.

Choose the Superworm CO 500 Count Live Superworms if…
Choose superworms for adults, as a treat or a way to deliver a supplement to a dragon that is being picky. Keep them at room temperature, because chilling kills them, and give them a piece of vegetable for moisture. They can bite, so feed from tongs or a dish rather than by hand, and never leave uneaten worms loose in the enclosure with a sleeping animal. Keep the frequency low enough that they do not displace the staple feeder.

A T5 10.0 UVB Fixture, the One Thing You Cannot Skip
Metabolic bone disease is the most common preventable illness in captive bearded dragons, and it comes down to inadequate UVB. A linear T5 tube across the basking side does what a coil bulb cannot, and the tube needs replacing roughly annually even when it still lights up.
Frequently Asked Questions
Can mealworms cause impaction?
The concern is regularly raised because of the hard exoskeleton, particularly for very young dragons and for animals kept on loose substrate. The clearest evidence of a problem is a dragon that is straining, has stopped passing waste, has a swollen abdomen or is weak in the back legs, and that is a veterinary situation rather than one to manage at home. Feeding appropriately sized prey from a dish on a solid surface removes most of the risk that is within your control.
Should I refrigerate feeder insects?
Mealworms tolerate refrigeration, which slows their growth and extends their useful life. Superworms must not be refrigerated, as the cold kills them. Roaches and black soldier fly larvae are kept at room temperature. Check the supplier's guidance for whatever you buy, because storing a feeder wrongly is the usual reason a tub arrives fine and is dead within a week.
What should the staple actually be?
For most keepers, gut loaded and dusted dubia roaches or black soldier fly larvae, with crickets, superworms, hornworms and others used for variety. For an adult, the larger part of the diet should be plants rather than insects at all. Ask your vet to assess body condition at check ups, since the commonest diet problem in adult bearded dragons kept by attentive owners is too much protein rather than too little.
