1: Insects are arthropods with three body sections, six legs, one pair of antennae, an usually one or two pairs of wings.
2: The three sections of an insect are the head, thorax, and abdomen.
3: Insects have compound eyes, which have many lenses.
4: Insects begin their life as eggs.
5: Then, metamorphosis changes them into an adult.
6: The two types of metamorphosis are complete and gradual metamorphosis.
7: You are probably familiar with complete metamorphosis. In this process, there are four stages.
8: They are egg, larva, pupa, and adult.
9: In the larva stage, the insect looks very different from the adult.
10: Next is the pupal stage. This is the "cocoon" we think of.
11: Finally, the pupa becomes an adult.
12: The next type of metamorphosis is called gradual metamorphosis.
13: Instead of the larva and pupa stages, there are two nymph stages.
14: These are the nymph and larger nymph.
15: Nymphs are small, growing versions of the adult insect.
16: If it was living, or it is living, some kind of insect will eat it.
17: Most insects have specialized mouth parts designed for the type of food they eat.
18: Insects have various ways of defending themselves.
19: The most common is camouflage.
20: Other insects closely resemble another organism.
21: There are 200,000 times more insects than people.
22: Some insect species can be helpful, while others can be harmful.
23: Many species may also carry disease.
24: However, the vast majority of insects are not harmful to humans.
25: Unfortunately for the ones that are, we humans have ways to get rid of them.
26: Biological controls are used to control insect populations.
27: Biological controls are natural predators introduced to the insect's environment.
28: These controls are much more effective and better for the environment than pesticides.
29: Pesticides are chemicals released into the environment to kill insects.
30: Unfortunately, these pesticides kill many other things besides insects.
31: DDT is a well known pesticide that nearly caused the bald eagle species to become extinct.
