Cockroaches are an ancient group of insects that have changed a little in appearance in 320 million years.There are around 4,000 species of cockroaches worldwide,and most live in tropical regions,preferring warm,humid,dark areas.These are creatures with flattened bodies,leathery wings,skittering legs,and long,waving antennae.Despite the fact that cockroaches cause annoyance to people,they can bring benefits to the environment.

        Cockroaches that often give some people the creeps are loathed for two reasons.First,they are considered filthy insects and may cause diseases.Since they eat garbage,their waste materials,containing dangerous bacteria that they spread around buildings and houses as they find their way around,cause adors and stains.In addition,their saliva and waste materials may cause allergies and aggravate asthma.Second,people think that to eliminate cockroaches is not easy because they reproduce fast and they are difficult to skill.For example,a German cockroach and her young can produce more than 300,000 cockroaches in one year.They are skillful at running from shoes,newspapers,and other instruments used to kill them,and several species are even resistant to insecticides.The success of their survival strategies is proven by the longevity of the group and its amazing diversity.

        Although they have a bad reputation,cpckroaches play an important role in ecology,a fact that many people are not aware of.They are generalist feeders,capable of digesting a wide range of substances due to the variety of bacteria and protozoa in their digestive systems.They help decompose forest litter and animal fecal matter,and in turn,other insects such as beetles and them and their eggs.They are,therefore,an important part of the food chain.
