How it works

These writing prompts about fireflies keep to one warm evening: a jar opened on the porch steps, one blink half a beat late on purpose, a bet on the summer's first firefly, a street that switches its lights off.

Firefly writing prompts in code

A code in flashes is the group no other insect could carry. Each kind of firefly has its own flash pattern, so these prompts ask for an invented code, a script between the air and the grass, and a mix-up between two kinds.

The facts under the lights

Twenty-eight prompts carry a fact from Wikipedia's firefly article or from National Geographic Kids. The light gives almost no heat, the larvae glow before they can fly, and the adults of most kinds live only a few weeks in summer.

  • Write a jar prompt twice, once from each side of the glass. Keep the version that surprised you.

Questions and answers

What is a good writing prompt about fireflies?

One with a message in it. A child with a flashlight tries to answer a firefly in its own code: write what happens. The firefly may come closer, go dark or say something the child cannot read.

Why do fireflies light up?

Mostly to signal other fireflies and find mates, National Geographic Kids says. To birds and toads the same flashing is a warning: fireflies taste foul, so predators rarely eat them.

Is a lightning bug the same as a firefly?

Yes. National Geographic Kids says fireflies are also known as lightning bugs, and that they are beetles. One prompt has two children argue over which name is right.

Why are there fewer fireflies?

Scientists are not sure how far the numbers have dropped, National Geographic Kids says, but pesticide use, loss of habitat and light pollution have likely played a part. Light at night gets in the way of the signals.
