What Makes a Lightning Bug Glow?
Lightning bugs, also known as fireflies, get their glow from bioluminescence. A chemical reaction in their bodies between oxygen, calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, causes them to light up.
They live in warm, moist areas of Asia and the Americas. And that’s why I remember them in the humid, summer days of my childhood in Ohio. And miss them now during the dry summers in California!!

How to Make Your Lightning Bug Paper Circuit Card
- Print out the template on white card stock. Color if using the blank template.
- Fold the card in half along the dotted line.
- With a pin, poke a hole through each black dot on the lightning bug tail all the way through to the circuit diagram.
- Insert LED with the positive lead (the longer one) in the left hole and the negative lead (the shorter one) in the right hole. Bend leads so the bulb is flat to the paper and the leads follow the circuit lines.
- Tape along the circuit lines with copper tape there are no breaks in the tape except at the LED and at the battery.
- Place battery on grey circle, negative terminal side down and fold the card at the dotted corner line. Secure with a binder clip.
Isn’t this finished lightning bug paper circuit card cute? I love this little glowing critter!
If you have a little kiddo who wants to do what the big kids do, grab some mini glow sticks and have them tape them to the card instead of building the circuits.
More Firefly Fun
We love the book How to Survive as a Firefly by Kristen Foote. It’s a fun story that teaches the amazing science behind why fireflies glow and how they survive throughout their life cycle.
