Disadvantages of Mealworms for Bearded Dragons

1.       Low Calcium

Mealworms are low in calcium, making them not the best source of this mineral for your pet. Bearded dragons need plenty of calcium to support their bones growth, development, and maintenance needs. When they don’t get enough calcium, these lizards might suffer from metabolic bone disease.

Metabolic bone illness is the most common disease among captive bearded dragons. Its signs include swelling in the hind legs, face, or mouth, shaking limbs, and lethargy. In severe cases, your bearded dragon might have deformities or experience muscle twitching. If detected early, metabolic bone disease can be treated, but you should prevent your pet from getting the disease in the first place.

A ratio ranging between 1.5:1 and 2:1 for calcium to phosphorus is ideal for beardies. However, this ratio is significantly lower in mealworms meaning that mealworms will not provide your bearded dragon with the ideal mineral ratio.

3.       High In Fat

Mealworms are rich in fats, even though you can’t tell by looking at them. If fed in plenty, your pet might become overweight or obese. Being overweight in beardies can cause serious health problems such as prolapses, organs dysfunction, and dystocia. Two of the most common indicators are the pet having a saggy beard or a stomach that drags on the ground as it walks.

Captive bearded dragons don’t exercise as much as they would in the wild. Therefore, they are bound to build up weight faster than they would in the wild. Feeding captive bearded dragons with mealworms puts them at an even higher risk.

Limit the number of mealworms, especially if you often give your bearded dragon other high-fat foods or treats.

On the other hand, hatchlings and baby bearded dragons should be fed with ¾ proteins and ¼ greens.

Upon getting to adulthood, you should reduce the number of mealworms you feed your bearded dragon and aim to provide it with a more balanced diet comprising green vegetables and proteins. Mature ones need to eat more green and less protein.
