Interesting insects taken from net



The Longest Insect
The Borneo walking stick (Phobaeticus kirbyi) can grow to up to 32 centimeters long, with another 14 centimeters if you measure the legs stretched out

The Biggest
Goliath beetles (Goliathus) are the largest insects in terms of bulk and weight. They can reach over 4 inches long

Strongest animal on earth.
The Hercules beetle (Dynastes hercules) is a species of rhinoceros beetle that lives in South America. It can grow to over 6 inches in length (counting its horns), but its claim to fame is its strength. The Hercules beetle can support 850 times its own weight on its shell! This beetles eats only vegetation and is not aggressive, except to other Hercules beetles, when males fight each other over females.

Weird Lifecycle
The twisted-wing parasite (Strepsiptera) is an order of insects who display a gruesome lifestyle. The larval stage parasite will climb a flower and wait for an insect pollinator (bee or wasp) to come along. They climb aboard the bee, burrow into its body, and change into a second-stage larva. They feed off the blood and organs of the host. An adult male parasite will emerge from the host and search for a mate -a process that takes such little time that he never develops a mouth. The adult female remains in the host’s body for the rest of her life, never growing legs or wings. She mates by pushing only her reproductive organs outside of the bee’s body! Her offspring will emerge and look for new hosts.

Violent Sex
The gruesome behavior or the male African bat bug (Afrocimex constrictus) is directed at other bat bugs. Instead of copulating via the female’s sex organs, he will stab her abdomen to release sperm directly into her bloodstream. So the females have evolved paragenitals, a “spongy reservoir of immune cells” as a defense against these tactics. But since male bat bugs are not particular when it comes to mating, some male bat bugs have also developed paragenitals to defend themselves against sexual attack!

Trap and Torture.
Tree ants (Allomerus decemarticulatus) in the Amazon contruct elaborate traps for other insects they feed upon. They build these traps from tree fibers reinforced with fungus. When an unsuspecting insect encounters the trap, the ants emerge from hiding underneath and pull the prey’s legs to immobilize them, almost like a torture rack. Then they dismember the victim and carry the parts off to the colony. This method of “drawing and quartering” allows the ants to dine on insects much larger than themselves.

Unstoppable Swarmers.
Driver ants (Dorylus) or siafu are the masters of the swarm. Dorylus includes several species of army ants, primarily found in Africa. Colonies can contain 20 million ants! When the column is on the march looking for food, people can avoid them just by stepping aside. But there have been cases where invalids have been killed (by asphyxiation) when a column of ants marches through the house. They have been known to kill and eat animals up to the size of small zebras.

Deadliest of all.
The mosquito (Culicidae) causes the deaths of millions of people every year. They spread yellow fever, dengue fever, encephalitis, West Nile Virus, and malaria from person to person, without being affected by the diseases themselves. They also transmit the debilitating filariasis worm, which can lead to elephantiasis in humans. Mosquitos are nasty business.
