Depending on the size of my silkworms, I give 6 to 10 once a week. I give 4 superworms (calcium dusted!) once a week. They have a poor calcium/phosphorus ratio as is. I feed large (3/4 inch) roaches, not adults, because adults contain more uric acid than roaches that are still growing (uric acid can contribute to gout). Im still working out the number of roaches...I think he could do more than the 6 or 7 I feed him, but Im trying to keep him leaner for health. Roaches also once a week. Calcium dust all bugs/worms except hornworms and if you feed them, the black soldier fly larva (also known as calciworms or phoenix worms). I dont feed crickets or wax worms. That is just a guideline...sometimes ill give roaches 2x week, or superworms 2xweek, or silkworms 2x week. Sometimes I mix them up..a couple of these, one or two of those. Variety is the key to get all the nutrients...I learned that here from a couple very experienced keepers!
