Last week I visited Emerald Park Elementary in Kent,
Washington. And during our school assembly we talked about what MUSES inspired
me to write HERBERT, my new book. Flies, honeybees, bullfrogs, and DRAGONFLIES
were just a few.
I showed some of my research on these MUSES and
thought I would share what I learned with you in the coming weeks.
If you have read my book, HERBERT, you know that the
DRAGONFLIES are the most feared creatures in the book. So, let’s take a look at
DRAGONFLIES and find out why they have such a SCARY reputation in the insect
world.
Looks like we have found our MUSE! DRAGONFLIES!
Dragonflies were some of the first insects to evolve
on Earth some 300 million years ago. So, while the dinosaurs were roaming, the
dragonflies were soaring.
But these dragonflies were a bit different than the
ones we see today. In shape, they were the same, but in size they were MUCH
larger. Today dragonflies have a wingspan of up to five inches, but prehistoric
dragonflies had wingspans of up to two feet! Some researchers believe there was
more oxygen in the air back then, which allowed things to grow BIGGER.
Take a look at this video. About half way through
you will see REAL fossils of these gigantic “flying dragons”!
WOW! Did you see the dragonfly emerging from the nymph stage of metamorphosis? Watching the wings unroll is one of the COOLEST things I have ever seen!
Dragonflies have three major life stages: egg, nymph
and adult. This is called metamorphosis. Butterflies also undergo
metamorphosis, but they have four stages: egg, caterpillar, chrysalis, and
adult.
Dragonfly eggs hatch underwater. The nymph dragonfly
may live underwater for a few years before climbing to the surface. And while
they are underwater, they are tiny predators. Take a look at this video to see
a dragonfly nymph on the hunt.
And the hunt doesn’t end here. Once dragonflies become adults they catch their prey in midair. In fact, if a dragonfly loses its ability to fly, it will die of starvation.
Dragonflies have expert flying skills. They can
hoover, fly straight up and down, and dart away at lightning speed (well at
least it looks like). These mini aviators have inspired engineers to try
building robots that can fly like dragonflies.

Not only can dragonflies FLY very well, they can
also SEE very well. Two gigantic eyes make up most of the dragonfly’s head.
These are eyes are called compound eye because they have 100’s of lenses
instead of just one lens like the human eye. This gives the dragonfly to see
every angle, except directly behind them. That’s why dragonflies are so hard to
catch!
Without these amazing predators we call DRAGONFLIES,
we would have A LOT more mosquitos. Dragonflies can eat up to 100 mosquitos a
day. That is 100 less mosquitos to feast on our blood. YAY, DRAGONFLIES!
There are nearly 5000 species of dragonflies. Some
dragonflies are adults, some live for only a few days, while others may live up
to a year.
With this new knowledge, what kind of story could
you write? Maybe these WHAT IF questions will help you get started.
WHAT IF your main character was a bug collector and
found a living prehistoric dragonfly?
WHAT IF your main character was a dragonfly who
craved jelly beans instead of mosquitos?
WHAT IF your main character built a dragonfly
helicopter?
The possibilities are endless, and please leave your
own what if questions in the comment section below. I’d love to see what you
come up with.
So, grab a cup of hot cocoa, a pencil and a piece of
paper, and let’s begin. With your imagination, we can go anywhere. I look
forward to seeing where you take us.

The word of the day is “metamorphosis”. Here is the
definition: a profound change in form from one stage to the next in the life
history of an organism.
