### From Simple English Wikipedia, the free encyclopedia

Assassin bug
Cicada

Bug is a word that is commonly, but incorrectly used for insects and insect-like animals, such as arachnids (spiders, scorpions), centipedes and relatives, sow bugs and sometimes worms.However, true bugs are the only animals that are really bugs. They are a large group of insects that are recognized by a piercing, sucking mouth. Bugs cannot chew. They pierce their food with their long, tubelike mouth called a proboscis. Then the bug pumps saliva through the mouth, which partly digests food(turns it into a liquid). Then the insect sucks up the liquid. Unlike butterflies and beetles, the life cycle of bugs doesn't have the pupal stage. This means that when a young bug hatches out of an egg, it looks like a small version of its parents. It slowly grows up to become an adult.

Some people think that all bugs are harmful or even dangerous. Some bugs are harmful; for example, bedbugs suck blood of sleeping animals, and aphids kill a lot of plants. But there are also helpful bugs. The assassin bug is one example. It captures and kills insects that harm different crops.Also, many people like to listen to the sound of male cicadas, who are the loudest insects on Earth. Many bugs don't help us in any way, but do not harm us, either.

Among some well-known bugs are water scorpions, assassin bugs, aphids,leafhoppers and cicadas.
