I'm having trouble breeding both B.lateralis and B.dubia. The the B.lats drop the egg cases all the time and bury them, but I have yet to see a single nymph in a month and a half. Also my B.dubia female carry a visible egg-case protruding from the abdomen, but I have yet to see any babies??? Both colonies are kept as pets in separate enclosures with about one-two inches of soil. Are the nymphs burrowing? Do they need more protein in their diet. Also, how long is Dubia gestation after eggcase is visible, and do the Dubias eat the egg cases while the mother is still carrying it??
