Photuris lucicrescens, the long crescendo Photuris, [2] July comet, big scary, [3] or big Lucy, [4] is a species of beetle in the Lampyridae family. [5] [6] It is found in the eastern United States. [1]
P. lucicrescens is a large firefly, with adults measuring 15–20 mm (0.6–0.8 in) long. They appear to be hunchbacked when viewed from the side. They have brown wing covers, or elytra, with wide light-colored side margins and stripes in the center of each side, starting from the shoulder and extending almost the entire length of the body. The head shield, or pronotum, is yellow, with a dark arrow in the center, which is often interrupted, appearing as two separate marks. The dark central mark is bounded by red or orange. Photuris fireflies have longer legs than species in the other common firefly genus in the United States, Photinus . The legs are pale close to the body. Lanterns are visible on the abdomen as pale segments. [3] [4]
Photuris has its origins in the Greek words for light, "phot", [7] and tail, or "ouros". [8] The specific epithet combines the prefix luci- from the Latin word for light [9] with the Latin root for crescendo, [10] describing this species' flash, which grows in intensity.
Beetles such as P. lucicrescens go through four life stages: egg, larva, pupa, and adult. Photuris fireflies spend the majority of their lives as larvae, which are bioluminescent. Larvae are predaceous, eating snails, worms, and other soft-bodied invertebrates. Adults appear in mid-summer, from June to August. [3]
Adult male P. lucicrescens fireflies fly over vegetation about 45 minutes after sunset and later, flashing to attract the attention of females. Their flash pattern is very distinctive, with a long, greenish flash that lasts as long as 2 seconds, increasing in intensity before ending abruptly. The firefly is dark for 3 to 5 seconds before it flashes again. Males also have a flash pattern that consists of a single, shorter flash, which is easily confused with flashes of other Photuris species. A female responds with an answering flash from low vegetation. Females also use "aggressive mimicry" to lure other species of fireflies in order to eat them. Because of this behavior, P. lucicrescens are one of the species known as "femme fatales". [3] [4]
This firefly can be seen in open fields and forests. [3]
P. lucicrescens is found throughout the eastern United States, as far west as Kansas and Oklahoma. [1]
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.
Photuris is a genus of fireflies. These are the femme fatale lightning bugs of North America. This common name refers to a behavior of the adult females of these predatory beetles; they engage in aggressive mimicry, imitating the light signals of other firefly species' females to attract mates – but Photuris use it to attract, kill and eat the unsuspecting males of those other species. Their flashing bioluminescent signals seem to have evolved independently and eventually adapted to those of their prey, mainly unrelated Lampyrinae, such as Photinus or Pyractomena.
Glowworm or glow-worm is the common name for various groups of insect larvae and adult larviform females that glow through bioluminescence. They include the European common glow-worm and other members of the Lampyridae, but bioluminescence also occurs in the families Elateridae, Phengodidae and Rhagophthalmidae among beetles; as well as members of the genera Arachnocampa, Keroplatus and Orfelia among keroplatid fungus gnats.
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.
Photinus pyralis, also known by the common names the common eastern firefly or big dipper firefly, and sometimes called a "lightning bug", is a species of flying beetle. An organ on its abdomen is responsible for its light production. It is the most common species of firefly in North America, and is typically found east of the Rocky Mountains. Photinus fireflies are often confused with fireflies of the similar-sounding genus, Photuris, which are also found in North America.
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.
Photinus carolinus, commonly known as the Smokies synchronous firefly, is a species of rover firefly whose mating displays of synchronous flashing have fascinated both scientists and tourists. As individual females synchronize with males nearby, waves of alternating bright light and darkness seem to travel across the landscape. Firefly displays typically occur in early June near Elkmont, Tennessee, in the Great Smoky Mountains National Park, near Gatlinburg. The species can be found in isolated pockets of the Appalachian Mountains in the eastern United States.
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.
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.
Photinus brimleyi, or sidewinder firefly, is a species of firefly in the Photinus genus. It is found in the southeastern United States.
Lucidota atra, the black firefly or woodland lucy, is a diurnal species of firefly — a member of the Lampyridae family of beetles.
Photinus cookii, or Cook's firefly is a species of day-active firefly in the beetle family Lampyridae. It is found in North America in the Eastern USA, including Florida and Texas.
Photinus consimilis, or cattail flash-train firefly, is a species of firefly in the beetle family Lampyridae. It is found in eastern North America.
Photinus indictus, or silent firefly, is a species of firefly in the beetle family Lampyridae. It is a diurnal firefly, active during the day rather than at night, with no lanterns. It is found in eastern North America.
Photinus tenuicinctus, or thinly-girdled firefly or Ozark spark, is a species of firefly in the beetle family Lampyridae. It is found in the Ozarks in Arkansas and Oklahoma.
Photuris mysticalampas, also called the mysterious lantern firefly, is an endangered synchronous-flashing firefly species described in 2013.
Abscondita chinensis, is a species of firefly beetle found in India, China and Sri Lanka.
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.
