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.
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.
The Cratomorphini are a tribe of fireflies within the large subfamily Lampyrinae. The genera placed in this tribe often contain well-sized members of their family. The larvae of many species climb trees to feed on snails. This group includes a few "lightning bugs" from North America, such as the genus Pyractomena. Further south in the American tropics, Aspisoma can be found.
The Lampyrini are a tribe of fireflies in the large subfamily Lampyrinae. The lineage formerly separated as Pleotomini seems to be a specialized offshoot of the Lampyrini not too distant from the type genus Lampyris and is therefore included here. This tribe occurs throughout the Holarctic and contains the typical "glowing" or "continuous-light" fireflies from that region. Some otherwise very advanced Lampyrini, like species in Paraphausis and Pyrocoelia, have degenerated light-producing organs again and communicate primarily or even exclusively with pheromones like the ancestors of the fireflies did.
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.
Pyractomena punctiventris is a species in the family Lampyridae (fireflies), in the order Coleoptera (beetles). It is found in North America, where it is known from east-central Texas south to Veracruz, Mexico.
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.
Brachylampis is a genus of fireflies in the family Lampyridae. There are at least two described species in Brachylampis.
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.
Pyractomena borealis commonly known as the Spring tree-top flasher is a species of firefly in the beetle family Lampyridae. It is found in North America, where it has a very wide distribution, as it is known from Alberta east to the Maritime Provinces of Canada, and south to all US states east of the Mississippi River.
Pyractomena lucifera is a species of firefly in the beetle family Lampyridae. It is found in North America.
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.
Pyractomena vexillaria is a species of firefly in the beetle family Lampyridae. It is found in Central America and North America.
Pyractomena ecostata, the keel-necked firefly, is an endangered species of firefly in the beetle family Lampyridae.
Prolutacea is a genus of fireflies in the family of beetles known as Lampyridae, containing a single described species, Prolutacea pulsator.
Pyractomena dispersa is a species of firefly in the beetle family Lampyridae. It is found in North America.
Pyractomena linearis is a species of firefly in the beetle family Lampyridae. It is found in North America.
Phausis inaccensa, also known as the shadow ghost, is a species of firefly in the family of beetles known as Lampyridae. It is found in central and eastern United States. The larviform females of the species are bioluminescent, whereas the males are winged but lanternless.
Pyractomena marginalis is a species of firefly in the beetle family Lampyridae. It is found in North America.
