Baby leos can eat any insect provided it is of the correct size. You should keep the diet varied and feed them every day, as much as they like. Adults should be fed every other day, enough to fill them up. If they stop hunting down food, or walk away from the dish of mealies, remove any extras. Obesity is common in leos, and over-feeding is one factor. Another is the kind of food being offered. Adults do well on crix, mealies, supers, silkworms, and the occassional pinkie during the breeding season. Butterworms and waxworms should be used ONLY as treats. They are high in fat with little else to offer. Be sure to use a good calcium D3 supplement at each feeding for babies, and every second feeding for adults. A multi-vitamin should be used aonce a week, perhaps more if you aren't providing adequate gut-load for your insects.
It's very difficult to overfeed leos, they stop when full, just watch that you provide the right kind of insects at the right time
