In the wild they will have a diverse menu of insects and other smaller critters to feed on. But in captivity, the best food is crickets, worms, and a variety of insects you can maybe find. To give you an idea of a proper amount of food. Emperor scorpion’s are a larger size scorpion and they will eat around 5-10 crickets a week. Remember to change it up every now and then.
Keeping Mealworms As Feed
Mealworms are the larvae of the darkling beetle. Mealworms, like all beetles undergo complete metamorphosis, and have an egg, larva, pupa and beetle stage. Females lay up to 1000 very small eggs, which quickly become coated in substrate. They remain at this stage for around a week depending on temperature.
The newly emerged larvae are very small but grow rather quickly, leaving an exoskeleton behind at each moult. Mealworms spend around 3 months as larvae, then they pupate, this stage only lasts around two weeks. The beetle that eventually emerges from the pupa is a light beige, darkening to red, brown, and finally black after about two days.
You need a shallow container such as Tupperware or a packed lunch box. Size isn’t too important but a container 25cm long x 15cm wide x 10cm high filled almost to the top with substrate can house around 30 beetles and 200 mealworms. If the container is too small then the beetles will find and eat many eggs. Ventilation is quite important, air holes in the lid are needed but should be kept small so the newly hatched mealworms can’t wriggle out.
The substrate you should use is bran, if you cannot get this rolled oats will also be good. It is recommended to feed vegetables or fruit on occasion but this isn’t essential. This is the means that the mealworms get their moisture. Make sure that the food does not mould, replace it if this should happen.
Don’t forget a small water dish for them too. They don’t need much at all. Just make sure its not too deep so they dont drown themselves.
