Madagascar Hissing Cockroach
Found in Madagascar.
The "horns" or bumps on the male's pronotum
are used in fights for breeding rights to the female.
It is very uncommon to see males fight unless you
observe them all of the time. They rely on noise-making
to defend them selves. They range from 1 1/2- 3
inches (4-7.8cm). Also males are usually much smaller.
Madagascar Hissing Cockroaches are called "glass
climbers" which mean that they can walk on
glass as if it was floor, just like Gecos. The best
thing to keep them from getting out of their enclosures
is Vaseline. Lubricate about 2 inches (5cm) from
the top of the enclosure with Vaseline, each time
they will try to climb on it they will just keep
on sliding back down. During growing up, the these
cockroaches change in to many different shades of
brown and black. Ones matured, they will give birth
to live babes every month.
