ALL ABOUT
INSECTS
Insects are the largest group
of animals on earth by far: about 926,400
different species have been
described. They are more than half of all
known living species. They may be over 90% of animal
species on Earth.
New species of insects are
continually being found. Estimates of the total number of species
range from 2 million to 30 million.
Insects have six legs; and
most have wings. Insects were the first animals capable
of flight. As they develop from
eggs, insects undergo metamorphosis. Insects live all over
the planet: almost all are terrestrial (live on land). Few insects
live in the oceans or in very cold places, such
as Antarctica. The most species live
in tropical areas.
Some people call all insects
"bugs", but this is not correct. Only some insects
are true
bugs, which is a
particular order of insects. People who study
insects are called entomologists.
Different kinds of insects can
be divided into groups called orders. There are many insect
orders. The biggest insect orders are listed
below:
Spiders, scorpions, and similar animals are not
insects; they are arachnids. Arachnids
are arthropods that have four pairs of
legs. Centipedesare also arthropods, but not
insects: they are in a subphylum called
the Myriapoda.
