1. definition of insects
Insects are any of a group of small and often winged animals that have six jointed legs and a body formed of a head, thorax, and abdomen. Also called a bug, creepy-crawly [British, informal], gogga [South Africa, informal].
2. BASIC FACTS
It is assumed that the class of insects originated about 480 million years ago. The first class of insects were land bound (only crawled on land). A part of the group later grew wings. The cockroach is the oldest living insect that has some resemblance of the pre-historic ancestors.
Insects live in different habitats on earth and in different weather conditions. They are found on land, in the air and even in water. They prosper in the hot deserts just as well as the icy cold snowy mountain streams. They are even found in dark places such as caves. Almost 97% of insects live on land.
At any given time, it is estimated that there are ten quintillion (10,000,000,000,000,000,000) individual insects alive. That's about 200 million insects for every human on the planet. Unfortunately this number is drastically coming down with some countries recording major losses in insect numbers.
The smallest known insects are from the Fairyfly family, with a body length of only 0.0055 inch (0.139 mm). The title for largest known insect in the world varies according to which measure is being used. If only length is looked at, certain stick insects can measure up to 14 inches (35.7 cm), and this excludes the legs! Overall, the Rhinoceros Beetle takes first prize when it comes to body size. It can measure up to 50 g (1.8 oz) in weight and 10 cm (3.9 in) in length. It can grow to 2 inches (5 cm) wide.
Sexual reproduction, which involves male and female individuals, is the most common form of reproduction among animals, including insects. However, some species of aphid, ant, parasitic wasp, bee, midge, grasshopper and stick insect can reproduce asexually, through a process called parthenogenesis. In this type of asexual reproduction, the female can generate an embryo without the help of a male's sperm.
More than half of all the insect species are herbivores, and feed on plants and sap. However, there are insects that prey on other insects and also those that are scavengers (eating the flesh of dead animals).
