- In some species, firefly eggs and larvae emit light.
- Fireflies are found on almost every continent except Antarctica.
- Fireflies don’t make tasty prey! When attacked fireflies shed drops of blood known as “reflex
bleeding.” The chemical is bitter and poisonous.
- Firefly larvae are carnivores and eat snails and worms. Yum!
- Fireflies emit light to attract a mate but also to defend territory and warn predators away.
- Fireflies have a 2-year lifecycle. The larvae overwinter in the soil.
If you collect fireflies in a jar, be sure the lid has air holes. Please be sure to release them, or they
will die. Before you let them go take them inside or near a bright light so you can see the insects well.
- Can you count how many legs they have?
- What do you notice about their wings?
- What colors do you see on them?
- Can you tell them apart?
Try taking a digital picture of fireflies flashing in your jar in the dark. Take another in the bright light.
