Yes, sugar gliders eat mealworms, and most love them. But mealworms are high in fat and phosphorus and low in calcium, so they should be an occasional treat, not a staple. Insects as a group are best offered in a small number every other day, dusted with calcium.
Why gliders need insects
In the wild, sugar gliders eat many insects and spiders for protein. Pet gliders still benefit from some insect protein, but the amount should be small and the type should vary.
The mealworm problem
- Fat: mealworms are fatty, and glider weight gain is common.
- Calcium balance: they contain far more phosphorus than calcium, which can contribute to weak bones if they dominate the diet.
- Hard shells: large or hard-shelled worms can be difficult to chew.
How to feed them safely
- Offer a small number, not a bowl full. Ask your vet what suits your glider’s size and weight.
- Dust live mealworms with a plain calcium powder before serving.
- Gut-load them with healthy greens or vegetables for a day or two beforehand.
- Buy from a pet or feeder supplier. Never feed wild-caught insects, which may carry pesticides or parasites.
- Use them as a bonding treat from your hand, but not every night.
Better insect variety
Crickets, dubia roaches and black soldier fly larvae have better calcium ratios than mealworms, and rotating them keeps meals interesting. Superworms are even fattier than mealworms, so use them sparingly.
Where insects fit
Insects belong in the fresh-extras third of the diet, alongside vegetables and a calcium supplement. See A Healthy Sugar Glider Diet and Calcium Supplements for Your Sugar Glider.
Bottom Line
Mealworms are a safe treat in small amounts, but not a main protein source. Dust them with calcium, rotate other insects and keep an eye on your glider’s weight.
