How insects grow
All insects begin life inside an egg.
(This female stag beetle does not have huge jaws for fighting like the male does. However, her bite is much more powerful than the male’s.)
The female insect usually lays her eggs in an out-of-the-way place, such as under a stone, leaf or bark, or in the soil.
When some types of insects hatch, they do not look like their parents.
(Large caterpillars always eat into the center of the leaf from the edge. Caterpillars grasp the leaf with their legs, while their specially developed front jaws chew at their food)
A young beetle, butterfly or fly is very different from a grown-up beetle, butterfly or fly. It is soft-bodied, wriggly and worm-like. This young stage is called a larva.
There are different names for various kind of larvae.
A fly larva is called a maggot, a beetle larva a grub and a butterfly larva is a caterpillar.
A female insect mates with a male insect before she can lay hen eggs.
(Caterpillars have three sets of mouth parts. The first are the Jaw-like mandibles that do most of ‘Hie work. They also have a second pair to pull food into the mouth. The final set are Joined together to form a lower lip.)
The female and male come together to check that they are both the same kind of ‘insect, and they are both and ready to mate.This is known as courtship.
Butterflies often flint through the air together in a ‘Courtship dance.’
Some kinds of insects change shape less as they grow up.
When a young cricket or grasshopper hatches from its egg, it looks similar to its parents.
However it may not have any wings yet.
The larva eats and eats.
It sheds its skin Several times So it can grow. Then it changes into the next stage of its life, called a pupa.
The pupa has a hard outer case that stays still and inactive. But, inside, the larva is changing body shape.
This change is known as metamorphosis.
The young cricket eats and eats, and sheds or moults its skin several times as it grows.
( This peacock butterfly has just emerged from its pupal case and is stretching its wings for the first time.)
Each time it looks more like its parent.
A young insect which resembles the fully grown adult like this is called a nymph.
At the last moult it becomes a fully formed adult, ready to feed and breed.
At last the pupa’s case splits open and the adult insect crawls out.
Its body, legs and wings spread out and harden.
Now the insect is ready to find food and also find a mate.
