There are many insects with a
Gradual Metamorphosis life cycle.
• Grasshoppers, termites, true bugs, aphids,
earwigs, thrips and book and bark lice.
Insects with Gradual Metamorphosis
have to be go through a nymph cycle.
Insects with Gradual Metamorphosis
have 5 nymph cycles. They don’t make a
chrysalis.
Click on the
number 5 to
see the five
nymphs.
Group 3 Insect Life Cycle:
Incomplete Metamorphosis
• The young insects in this group change shape
gradually. They do not look like adults until
shedding their last skin. Then there is a
change.
Incomplete Metamorphsis
Click on the 5instar
nymph and it will turn
into a dragonfly when it
climbs out his skin.
A dragonfly, mayfly, and a stonefly are all insects
with two sets of wings. They have an
Incomplete Metamorphosis life cycle. They
turn into the adult after they shed their last skin.
Group 4 Insect Life Cycle:
Complete Metamorphosis
• Some insects go
through 4 stages of
growth. None of the
young look like the
adult. Click on the
adult.
This is the adult.
Stage 1: These are butterfly eggs.
• Butterflies lay their eggs
on the leaf of the plant
that they eat.
• Look on the leaf of a milk
weed to find some eggs
of the Monarch butterfly.
• Click to watch where the
Monarch butterfly lays its
eggs.http://www.youtub

Stage 2: When the egg hatches a
little caterpillar comes out.
A new caterpillar is called a 1instar.
It is really little.
The caterpillar eats and grows and
changes into a 2instar and then a
3instar.
Stage 3:
The 5instar caterpillar is ready
to make a chrysalis.
Here are some different spun pupas.

the cocoon. http://www.youtube.com/watc

Stage 4:
The pupa opens up and out
comes the butterfly.
It looks different! It doesn’t look like
an egg, or a caterpillar or a pupa.

cocoon open up.

Caterpillars change 4 times. When they turn into a
5instar they are ready to make a chrysalis.

Now that you know about the life cycles of insects here
are some other fun curiosities about insects.
Some caterpillars look really scary, but don’t worry.
They are using a scare tactic so they will not get eaten.
Click on the link to see the scariest caterpillar of all in action.

More scary caterpillars!
Remember these caterpillars are trying to survive. They
don’t want to be eaten by a bird.
Oh! Oh! Sometimes another butterfly tries to copy a
. This is called mimicry.

Monarch butterflies taste nasty and birds won’t eat them. The Viceroy
butterfly tries to look like the Monarch so birds won’t eat him. Click on
the pictures to find which is which.
Look at the hind wings. The
Viceroy has an extra black line
going across the wings.
Look at the hind wings again. The
Monarch does NOT have an extra
black line going across.
Here is an other example
of insect mimicry.
The syrphid fly looks like the yellow jacket wasp. Can you see the
difference? Click on each picture to find what it is.

The moth
Jumping spider
This moth is using mimicry to look like a jumping spider.
The moth is also trying to scare the attacker.
Sometimes when you try to find insects, they are hard
to see because there is something called camouflage.
Camouflage is a disguise that causes the
insects to blend in with their surroundings.
Click on the pictures to
find the insects.
Look closely and click on the pictures
to find the camouflaged insects.
Can you find the insect? Look closely.
Remember they look like they blend in with
the surroundings.

Let’s see if we can remember some of

won’t get killed or eaten by an animal.
