Larvae usually eat snails and worms. Some species of fireflies feed on other fireflies—most notable is the genus photuris , which mimics female flashes of photinus , a closely related species, in order to attract and devour the males of that species. But adult fireflies have almost never been seen feeding on other species of bugs.
They may feed on plant pollen and nectar, or they may eat nothing. An adult firefly lives only long enough to mate and lay eggs—so they may not need to eat during their adult life stage. The larvae usually live for approximately one to two years, from mating season to mating season, before becoming adults and giving birth to the next generation.
Sometimes male photuris imitate male photinus to attract females of their own species. She shows up looking for food, but instead he gets a mate. Even more interesting, scientists believe some photinus males imitate photuris females giving off bad impressions of photinus male flashes, scaring off other photinus males and reducing competition.

You are here Home. Lightningbugs Encyclopedia Article. Description of Lightningbugs Unfortunately, the common, pleasurable summer pastime of collecting lightningbugs all too often fails to elicit the most rudimentary of questions about firefly biology. Interesting questions, huh? Life Cycle of Lightningbugs Like all beetles, the fireflies have a complete life cycle consisting of four stages: egg, larva, pupa and adult. Lightningbug Behavior Lightningbug larvae and adults produce light by an interesting reaction of chemicals and enzymes.

Perhaps because we are so familiar with them, either from growing up chasing them or seeing them portrayed in art, film and books, we may think that we know all about these simple insects.
Yet our flashy friends have a dark side that includes little-known tales of deception, poisoning and death. As summer approaches, here are 11 cool things about fireflies that you might not know. Fireflies are beetles. Whether you call them fireflies or lightning bugs, these insects are neither flies nor true bugs. Instead they are beetles, just like ladybugs and rhinoceros beetles. Like other beetles, fireflies have a pair of hardened wing cases, called elytra, that the wings fold underneath.
The elytra open for liftoff like gull-wing doors on a car, freeing the wings for flight. There are more than 2, species of firefly worldwide. Fireflies are found all over the world, on every continent except Antarctica—and they are incredibly diverse.
There can be many species sharing just one habitat. In fact, you are probably looking at multiple species when you are watching them in your own yard. Flashes are the firefly language of love. Fireflies use flashes as mating signals. The flashes that you see in your yard are generally from males looking for females.
They flash a specific pattern while they fly, hoping for a female reply. If a female waiting in the grass or bushes likes what she sees, she responds back with a flash of her own.
Each species has its own pattern—a code that lets individuals identify appropriate mates of the same species.
