DIET The diet of a mealworm beetle is wide and varied and they are not fussy eaters requiring a specific diet. Darkling beetle and mealworm diet can be broken down in to 3 sections. Carbohydrates protein and moisture. Carbohydrates- Bread oats and nuts are recommended as the main source of carbs for the insects. They should also be fed vegetables for extra carbs and micro nutrients. Protein- The most overlooked part of any insect diet is protein. Many insect keepers make the mistake of giving no protein source whatsoever, this mistake leads to cannibalism and egg eating as well as less egg production and laying. I would recommend dry or wet cat or dog food. If the food is dry it will need to be crushed first. You can also use nuts, soybeans and or milk powder. Moisture- Insects can get all of there moisture from vegetables. I would recommend cucumber as the best source for this but almost every vegetable can be used but you should avoid citrus and acidic fruits. You could also mist to keep the insects more healthy. Bug gel could also be used but can be expensive. Bug gel will eliminate food molding.
