Making It
Work
Engineers are people who find new ways
to make things work. They build bridges.
They dig tunnels. They make roads. They also
plan how to build toys, forks, cars, and more!
Some of the best engineers never went to college.
They were born knowing how to build things. But
these engineers arent people they are bugs!
Imagine a creature that can grow its own armor.
What about a bug that can make silk that is stronger
than steel? Insects can make structures as amazing
as our biggest skyscrapers. Some use materials they
find in nature. Others build things using their own
bodies! These are not aliens from a science-fiction
movie. These animal engineers build new things
on Earth every day.
A spider builds a silk
case for its eggs.

Every animal needs to find ways
to survive. All animals must search for
food. All creatures must find safe places to
live. Insects must avoid predators. But what
exactly is an insect?
An insect breathes air. Its body is divided into
three parts: head, thorax, and abdomen. It has
three pairs of legs. And it has wings.
Insects are a type of arthropod. They have
exoskeletons and jointed legs. Spiders are
arthropods. Crabs and some sea creatures are, too.
Around the world, these bug engineers have built
small structures that help them survive in a big way.
Spittlebug
Spittlebug is the name given to
the froghopper in the nymph stage
of development. The spittlebug is an
insect that makes bubbles that look like
spit. (Thats where it gets its name.) First,
it makes a big glob of froth. Then, it sits
inside it. That is where it grows into an adult.
The froth hides the bug from predators. And
those who attack the spittlebug will learn that
the froth has a very bad taste.

Super Spit
This spittlebugs froth does more than hide the nymph.
It also keeps the nymph at the right temperature and
prevents the insect from drying out.
