Hey there! Are you ready for a cool story about a real-life adventure? This is the tale of the Peppered Moth, a little insect that went through some big changes!
A long time ago, most peppered moths had wings that were white or gray with tiny dots, like pepper. These moths are night owls, meaning they stay awake at night and sleep during the day. When they rest, they like to hang out on trees, especially birch trees. Birch trees have light-colored bark with dark spots, and they often have something called lichen growing on them, making the bark even lighter.
Because of their light wings, the moths could blend in with the trees. This blending in is called camouflage, and it helped them hide from birds that wanted to eat them. But not all moths had light wings. Some had dark wings with light spots, and they were easy for birds to see against the light trees.
About 200 years ago, something big happened. People started building factories during a time called the Industrial Revolution. These factories burned coal for energy, and the smoke made the air dirty. This dirt made the birch trees darker, like they were sprinkled with coal dust. The lichen died because of the dirty air, so the trees lost their light color.
Now, the light-winged moths couldn’t hide well anymore, and birds could easily spot them. But the dark-winged moths could blend in with the dark trees, so they were safer. More dark-winged moths survived and had babies, which also had dark wings. Over time, there were more dark-winged moths than light-winged ones.
This change in the moths is called natural selection. It’s when animals with traits that help them survive have more babies with those same traits. That’s how the peppered moths went from mostly light wings to mostly dark wings.
But the story doesn’t end there! People realized the factories were making the air dirty and found better ways to make things without polluting. The air got cleaner, the birch trees became lighter again, and the lichen grew back. Now, the dark-winged moths stood out, and the light-winged moths could hide better. Natural selection happened again, and today, light-winged moths are more common.
The story of the peppered moth shows us how animals can change over time to survive. This process, called natural selection, happens with all living things, even if it takes a long time to see. It’s how humans became good at running and how rats got great at smelling. The world is full of amazing examples of natural selection!

Camouflage Hunt: Go on a nature walk with an adult and try to find animals or insects that use camouflage to blend into their surroundings. Look for butterflies, beetles, or even birds. Draw a picture of what you find and describe how their colors help them hide. Discuss with your adult how this helps them survive in their environment.
Moth Craft: Create your own peppered moth using paper and crayons or markers. Make two moths: one with light wings and one with dark wings. Find a spot in your house or yard where each moth can blend in. Take turns with a friend or family member hiding the moths and trying to find them. Talk about which moth was easier to find and why.
Story Time Reflection: Imagine you are a peppered moth living during the Industrial Revolution. Write a short story or draw a comic strip about your adventures trying to stay hidden from birds. Think about how you would feel when the trees changed color and how you would adapt to survive. Share your story with your class or family.
