| The name Lampyridae comes from the Greek word λαμπίς, meaning "torch".[1] The family includes fireflies and glowworms. Most fireflies are nocturnal, although there are a few species that are diurnal. Fireflies emit light from their abdomens to attract mates. The light show is used to identify species and also occurs when the firefly is disturbed. Some species produce sounds that accompany the light show. The larvae of fireflies are called glowworms. Glowworms are found in dark, moist places, such as under bark, in caves, and in the roots of plants. They emit a greenish light. | |
| The Lampyridae are a family of insects in the beetle order Coleoptera, with more than 2,000 described species, many of which are light-emitting. | |
| The fireflies are a familiar example of this family. These beetles are bioluminescent, emitting light from their abdomens in a variety of colors. | |
| Lampyridae are found in many different habitats, but most species live in moist areas such as forests, marshes, and swamps. A few species, such as fireflies, live in drier areas. Lampyridae are most active at night, and they use their light to find mates, prey, and danger. The light of a firefly is produced by a chemical reaction that takes place in special cells called photocytes. The light is emitted when an enzyme called luciferase catalyzes the oxidation of luciferin. The light is usually yellow, but some species produce green, blue, or red light. Fireflies are found in temperate and tropical climates. In the United States, there are about 90 species, most of which are found in the eastern half of the country. The most famous firefly is the Photuris pennsylvanica, which is found in Pennsylvania. | |
| they have been used as models in studies of optics and natural history. Fireflies are found all over the world. They are a type of beetle and their name comes from their ability to produce light. People have been fascinated by fireflies for a long time. They have been studied for their optics and natural history. |
