If there is a running race between insects, Cockroach is a sure medal winner. The cockroach starts off with all its feet on the ground, but soon switches to bipedal run (only two feet touching the ground) in seconds to reach high velocity. Scientists used special photographic technique to see and understand the cockroach in motion. It is the bipedal run that makes the insect move fast.
2. Wasp Nest
Wasps construct nests that consist of portioned chambers are cells. The mother wasp lays a single egg in each cell. It catches a specific number of caterpillars and places them in the cell before sealing the cell. When the larva hatches from the egg it has the food ready to feed upon and grow. The mother wasp of the genus, Eumenes provides five caterpillars to the egg that would hatch into a male and ten caterpillars to the one that would hatch into a female. The reason is, the female wasp is larger than the male and hence requires more food. Eumenes wasp is able to count the caterpillars besides distinguishing its eggs that would hatch into males or females.
3. Assassin Bugs
Assassin bugs are predatory insects. They have a beak like extension from the mouth called rostrum. The bug has jack-knifed forelegs that assist in grabbing the prey. Once the prey is tightly held, the assassin bug forces its rostrum and pierces the body of the prey injecting a strong digestive juice. A cockroach will die in just 3 to 4 seconds. The digestive juice converts the body parts of the prey into a fluid. The bug sucks the fluid through its rostrum and fills its stomach.
4. Dung Beetles
Dung beetles occur wherever dung is found. Their main food is animal dung though some scavenge carcasses or feed on decaying organic matter and fungi. There are three types of dung beetles, the rollers that roll dung into balls, the tunnellers that bury dung and the dwellers that live in heaps of dung or manure. The rollers usually consist of two beetles, one male and one female. The male rolls the ball while the female follows behind. In some smaller species only one beetle will roll the dung ball. It will follow a straight line irrespective of the obstacles in the path.
5. Jumping Fleas
There are more than 1500 species of fleas. All the fleas are known for their jumping ability, but the champion among them all is the catflea. The catflea can leap to a height of 34 inches. Scientists regard this as an incredible feat when considering the body size of the flea relative to the height of the jump. In comparison, the Space shuttle is slower in its take off and acceleration.
