CLASSIFICATION
Lightning Bugs are the same as Fireflies. They are members of a particular family of the Beetle Order. The Firefly Family is technically known as the Lampyridae.
Lightning Bugs are beetles. They can't be "flies" as their name suggests because "flies" are members of the Fly Order. Glow-worms, which produce light similar to Lightning Bugs', also are beetles, but they belong to a different though closely related family, the Phengodidae. There are many Lightning Bug species.
