The Lampyridae are a family of elateroid beetles with more than 2,000 described species, many of which are light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly during twilight, to attract mates. Light production in the Lampyridae is thought to have originated as a warning signal that the larvae were distasteful. This ability to create light was then co-opted as a mating signal and, in a further development, adult female fireflies of the genus Photuris mimic the flash pattern of the Photinus beetle in order to trap their males as prey.
Phausis is a genus of firefly beetles. These beetles are for the most part unimpressive in their appearance and behaviour, so have not drawn much study, and little is known about many of the species. Species in this genus are at least known from North America. Ten species are described in North America, ranging throughout much of the continent.
The Photurinae are a subfamily of fireflies (Lampyridae). They contain many of the well-known North American species, such as the Pennsylvania firefly, state insect of Pennsylvania. They are among the "flashing" fireflies known as "lightning bugs" in North America, although they are not too distantly related to the flashing fireflies in the Lampyrinae; as the most basal lineages of that subfamily do not produce light at all, the Photurinae's flashing signals seem to be convergent evolution.
Photuris pensylvanica, known by the common names Pennsylvania firefly, lightning bug, dot-dash firefly and glowworm, is a species of firefly from the United States and Canada. It is also widely known under the Latin name Photuris pennsylvanica, although the original spelling, with one "n", was common in Latinized names of the time and remains the valid name.
The rover fireflies (Photinus) are a genus of fireflies. They are the type genus of tribe Photinini in subfamily Lampyrinae. This genus contains, for example, the common eastern firefly, the most common species of firefly in North America.
Photuris versicolor, is a species complex of firefly common throughout the Eastern United States. Fireflies famously use flash-based visual signalling to find mates at a distance and each species of firefly has a unique flash pattern sequence that males and females of the same species use to identify one another. Researchers have documented the ability of female P. versicolor to hunt males of other firefly species by mimicking the flash responses of female fireflies of other species. Photuris versicolor appear to target males, such as Photinus pyralis, specifically for the lucibufagin steroids that their prey produce.
Ellychnia corrusca, the winter firefly, is a species of firefly in the genus Ellychnia. It is a lantern-less diurnal beetle common in the United States, Mexico, and Canada. The adults spend winter on a colony tree, favoring Quercus (oak), Carya (hickory), and Liriodendron tulipifera.
Photinus consanguineus, or double cousin firefly, is a species of firefly in the genus Photinus. It is found in eastern North America.
Pleotomus nigripennis is a species of firefly in the family Lampyridae. It is found in North America.
Photinus macdermotti, or Father Mac's firefly or Mr. Mac, is a species of firefly in the family Lampyridae. It is found in North America.
Pyractomena is a genus of fireflies in the family Lampyridae. There are at least 20 described species in Pyractomena.
Pleotomus is a genus of fireflies in the family Lampyridae. There are about five described species in Pleotomus.
Aspisoma ignitum is a species of firefly in the family Lampyridae. It is found in the Caribbean, Central America, North America, and South America. Its presence is uncertain in the United States.
Aspisoma is a genus of fireflies in the family Lampyridae. There are at least 70 described species in Aspisoma.
Pyropyga is a genus of primarily North American fireflies in the beetle family Lampyridae. There are about 13 described species in Pyropyga. It is among the genera of Lampyridae where both sexes of adults have no bioluminescent organs.
Micronaspis is a genus of fireflies in the family of beetles known as Lampyridae, containing only one species, the Florida intertidal firefly. It is found in the Bahamas and Florida. It is threatened by habitat loss from coastal development as well as storm surges and sea level rise as a consequence of climate change, with Hurricane Dorian having a major impact on Grand Bahama island, where the species is known from. Increased chemical and light pollution has also seriously affected the species. Further threatening it in Florida is the introduction of Steinernema carpocapsae as a biocontrol agent for crops, which is known to target other beetle species than the ones it is meant to control; it is likely the cause of a local extirpation of a population of M. floridana from Sarasota Bay.
Photuris fairchildi is a species of firefly in the beetle family Lampyridae. It is found in North America.This species is known to use aggressive mimicry in order to lure in and prey upon the males of other species of fireflies. This species inhabits marshes, spruce forests, and other low-lying swampy areas.
Pterotus is a genus of fireflies in the beetle family Lampyridae. There are at least two described species in Pterotus.
Photuris lucicrescens, the long crescendo Photuris, July comet, big scary, or big Lucy, is a species of beetle in the Lampyridae family. It is found in the eastern United States.
Photuris hebes, commonly known as heebie-jeebies or the slow-hitch firefly, is a species of beetle in the Lampyridae family. It is found in the eastern United States.
