Hornworms, butterworms, silkworms, reptiworoms (phoenix worms), dubia roaches, crickets. Those are all really good. Hornworms and silkworms have a certain food they eat. Butterworms stay in the fridge. Dubia and crickets need gutloaded. All should be dusted with the correct supplements. Reptiworms just stay in the cup and are good for two weeks.
