Introduction to Mealworms


Mealworms, the larvae stage of darkling beetles (Tenebrio molitor), are commonly used as a feeder insect in the reptile-keeping community. These small, worm-like creatures have a distinct appearance, with segmented bodies and a tough exoskeleton. In terms of nutritional composition, mealworms are rich in protein and fat, making them an attractive food source for many reptiles.


Mealworms have gained popularity as a staple feeder for reptiles due to their availability, affordability, and nutritional value. They are commercially bred and readily accessible in pet stores and online retailers, making them a convenient option for reptile owners. Moreover, their high protein content makes them a desirable choice for providing the necessary building blocks for growth and overall health in reptiles.


Feeding mealworms to crested geckos offers potential benefits and drawbacks to consider. On the positive side, mealworms are a convenient and easy-to-handle food source. They can be gut-loaded, meaning they can be fed nutrient-rich foods prior to being offered to the geckos, enhancing their nutritional value. Additionally, mealworms provide an opportunity for geckos to exhibit natural hunting behaviors, stimulating their natural instincts.


However, there are some drawbacks to feeding mealworms to crested geckos. One concern is the relatively high fat content of mealworms, which may not align with the geckos’ dietary needs, particularly if fed excessively. Additionally, mealworms have a hard exoskeleton that can be challenging for some geckos to digest, potentially leading to gastrointestinal issues if consumed in large quantities. Lastly, there is a risk of impaction if geckos consume mealworms that are too large or if their feeding is not properly monitored.
