I learnd that Madagascar is an island home to fascinating insect, Madagascar hissing cockroaches.
Madagascar hissing cockroaches are wingless insects, shiny brown in color.
They are oval-shaped and have a single pair of antennae.
It is approximately 2 to 4 inches in length and weighs ¼ to 7/8 ounces.
These cockroaches live in colonies of roaches of all ages and sexes.
The male cockroaches are larger than the females.
The males have a pair of horns on their head.
Madagascar hissing cockroaches have a wired way of giving birth to its young.
Females carry a cocoon-like case known as ootheca.
They carry their eggs in this ootheca and their neonatal nymphs inside their body(The nymphs are pushed outside the body by the females after they hatch.)
This gives an appearance as if she is giving birth to live young.
The roaches have a gradual metamorphosis stage, that is, development as eggs, nymphs and final adult stage.
These cockroaches can breed for 2-3 years or even longer. They commonly have two-three broods a year.
COCKROACHES AS PETS-
Madagascar hissing cockroaches can prove to be great pets. Unlike the other cockroaches, these cockroaches do not infest human habitats and are not pests. They survive on the jungle floors hiding under the leaves, logs and rocks. They are active during the night as these are nocturnal creatures. These scavengers do not bite and an easy to care for pet. They slowly walk on your hand and do not harm you in any way. You can even train your roach to run a maze or step on a lever. During the active period, use food or water and train him to do such simple tricks. (from http://www.buzzle.com/articles/madagascar-hissing-cockroaches.html
