    They are not usually dangerousto humans, but some insectshave stings that hurt. Others cancut your skin and make it bleed.

    Some of the insect fossils inrocks are 300 million years old.

    Some insects are vegetarians:they eat green plants and wood.But some of them eat otherinsects, evenbigger ones. Andsome insects, likethe praying mantisfemale, eat themale after mating!

    The praying mantis gets its name from the way it holds itsfront legs. These look like hands together in prayer.

    It lives in warm climates all over the world: SouthernEurope, Africa, South America, and Asia. Mantids (the pluralof mantis) usually live alone. Other insects are afraid of them,because they catch them and eat them.

    There are about 1,800 different kinds of mantids. Someare green or brown, and are very difficult to see on a leaf or aplant. Others look like colourful flowers purple or blue.

    The mantis does not hunt for food. It waits for otherinsects to come near, and does not move at all.

    When another insect comes near, the mantis shoots out itsfront legs and holds the insect tight. The poor insect cannotescape because the mantis has little hooks on its legs. Thesehelp it to hold the insect. Itstarts eating the insect from thehead, so the insect does not fightfor long, but dies quickly. Somebig mantids are strong enough tokill and eat frogs and birds.

    The mantis also uses its longfront legs to protect itself. Its legs are very sharp, and can cut the skin of a human being.

    Some bugs hunt for food not forthemselves, but for their babies.

    The wasp here is taking a weevilto its nest. Poor weevil!

    A wasps nest is made from a kindof paper. The wasp chews dead woodand the stems of plants, and mixesthese with its saliva. The result, whendry, looks like grey paper.

    Hairy foodThe spider-hunting wasp catchesvery big spiders for its babies.The fight between a wasp and abigger spider is exciting, but theresult is always the same. Thewasp is always the winner!

    This is what happens to the weevil. The wasp stings theweevil, but it doesnt kill it. It paralyzes it, so it cannot move.Then it pulls the weevil to its nest. This can be many metresaway a long way for a wasp!

    The wasp then lays an egg in the nest, and goes away.When the larva comes out of the egg, it begins to eat theweevil. The weevil is excellent food.

    The larva becomes very fat, and changes into a wasp.Then the cycle begins again.

    Some ants produce acid that can kill another insect.When the insect is dead, the ants carry it back totheir nest. If the insect is big, the ants sometimes cutit into two pieces, so that it is easier to move. This ishappening in the picture here. The little ants arecutting up the big insect.

    Not all ants eat meat: some are vegetarian, andeat leaves, and seeds, and fungus.

    It grows most in summer, when the water is warmand there is a lot of food. The nymph turns into anadult dragonfly. This beautiful insect lives in the airfor a few weeks, lays its eggs, and then dies.

    Dragonflies eat most of the time! They are very good hunters,because they can see the food coming from all directions.This is because they have all-round vision from their big eyes.

    Their legs hang down like little baskets, and they canhold onto the food. They can catch small insects, and eatthem, and fly ... all at the same time! But they take biggerinsects to a resting place at the side of the pond to eat.

    They can eat their own body weight in abouthalf an hour! Think of this. Think of your ownbody weight! How many kilos is it? Then thinkof half those kilos Is it possible for you to eatthat in half an hour?

    Ancient insectDragonflies are very old older thandinosaurs. They look the same now as230 million years ago. The piece of rockhere shows a perfect dragonfly shape,exactly the same as todays dragonflies.

    Kissing bugsSome assassin bugs are calledkissing bugs because theyoften bite people on their faces.This is probably because theskin on the face is soft, notbecause the bugs love people!

    Assassin bugs produce a poison that they can inject into theirvictims. This poison does two things: it kills other insects andit turns the victims insides into a kind of soup!

    Then the assassin uses the pump in its head to suck thesoup into its own digestive system. The poison does not hurt

    the assassin. It has a clever trick.It produces poison but it can alsoproduce a non-poisonous fluid.This fluid cancels out the poison!

    The assassin uses the non-poisonous liquid to wash itsmouth after it injects poison intoanother insect.
