Which insect is commonly known as a firefly?

Explanation:
Fireflies are glow-producing beetles in the Lampyridae family, and in many places they’re commonly called lightning bugs. The glow isn’t from a true fly; it’s a bioluminescent signal used to attract mates, with larvae also able to glow. That makes the matching option the correct one: the insect referred to as a firefly is the lightning bug. The Luna Moth, Long-Horned Grasshopper, and Mealybug do not glow and are not fireflies.
