Nymph Care: Please Note: The Carolina mantis is a great hunter and can display very beautiful shades of green. The nymphs we sell have been well looked after from the moment they hatched. To keep your nymphs(s) healthy you should keep these points in mind: You should lightly mist the sides of your habitat every second day. Do not over feed your nymph(s). Add no more than 5 to 10 flies to the habitat every two days. If there are still flies in the habitat on the second day wait another day before you add more flies. Keep this in mind. If your mantis is surrounded by too many flies, he will stress and die. They need moisture to shed. Always make sure the coconut fiber at the bottom of the habitat is moist at all times. Try not to handle the nymph(s) until they reach the L-6 or L-7 stage growth. Finally, keep the habitat away from direct sunlight and extreme temperatures.
