Cockroach labeled diagram game quiz for children to practice online. Have fun while learning about cockroaches.
Even though cockroaches have a reputation for being dirty creatures, they are actually amongst one of the cleanest insects out there. Cockroaches often groom their parts to remove dirt and other particles.
Cockroaches are arthropods – they have segmented bodies protected by a tough, chitinous armor called their exoskeleton. Sclerites are the hard plating on the surface of the exoskeleton.
We can divide the body of a cockroach into three distinct segments – the head, thorax, and abdomen.
The cockroach’s head is triangular, possessing a pair of compound eyes and a pair of long antennae which are able to feel and smell the bug’s surroundings.
Its thorax is separated into three regions – the prothorax, mesothorax and metathorax, each of which contain one pair of its six legs. The prothoracic legs serve as brakes as the cockroach moves, while the mesothoracic and metathoracic legs control its speed.
The mesothorax and metathorax each also house one pair of the cockroach’s wings. Many people receive quite a shock witnessing how quickly a cockroach can fly with these powerful organs.
The abdomen is mostly responsible for reproduction, containing the cockroach’s genital pouch for fertilizing and laying eggs.
Cockroaches undergo an incomplete metamorphosis, consisting of three distinct stages: egg, nymph and adult. A mature female lays eggs in an egg case called the ootheca. After a few weeks, the eggs hatch into the nymph. The nymph looks like an adult and can move around but do not have wings. They will shed their skin several times and develop into adults.
Cockroaches are usually found living in dark and obscure places like cracks in a home, under abandoned places in a home, septic tanks, garbage cans and places full of rubbish. They are nocturnal and seem afraid of light. They are a nuisance in homes, that is why humans use insecticides to eliminate them from homes. However, they serve as a vital source of food to birds and chickens.
