Mantids

Are also called praying mantis can be easily distinguished from the cockroaches by their strongly-spined raptorial front legs, and their long, narrow prothorax which forms a moveable neck. They can be up tp 150 mm long. And are usually well camoflaged to blend in with the plant stems and leaves. All mantids are carnivorous and use their front legs to catch their food. They will eat whatever they can hold on to, and even the very hardest parts of some beetles and wasps pose no problem to their very strong jaws which just keep munching through hard and soft parts. Their main prey is insects. Male mantids are usually smaller than the female, and may end up as a post-coital meal for the female, but this occurs more often in captivity than in the wild. The eggs are laid in oothecae (egg cases). The egg case and eggs are pumped out of the abdomen as a frothy substance. This hardens on contact with the air to a tough material. On the left you can see a female next to the egg case she has just attached to some twigs. During her lifetime a healthy, well-fed female can produce a dozen or more oothecae. When the young hatch they resemble small worms, but soon moult into small versions of the adult form. When kept in captivity mantids should be separated as soon as they hatch or else each cage will soon contain just one well-fed mantid! In captivity they can be fed on flies or crickets or anything that moves. I have even had one attempt to dine off my finger in preference to the small, juicy fly I was tempting it with.
