As old as an insect
We know that
insects were around
40 million years ago
because some were
trapped in a tree resin
called amber, which
hardened back then
and preserved them.
Red food dye:
this food
colouring is made from
the bodies of scale insects.
Silk:
believe it or not, the
silk you wear is made by
silk-moth caterpillars!
Honey:
if there were
no bees in the world,
we would have no honey.
Food:
to some people,
such as the Australian
aborigines, grubs are a meal.
Useful insects
Here are some other
ways that insects
are useful to us.
Introducing insects that
eat other insects is called
biological pest control.
Aphids
breed so
quickly that it
is difficult to
control them.
Pest control
Sometimes insects, such as
aphids, eat huge amounts of
our crops. The best way to get
rid of them is to introduce
another insect that likes
to eat them. Ladybirds
are often used for
aphid pest control.
