Photurinae
The Photurinae are a subfamily of fireflies ( Lampyridae). They contain many of the well-known North American species, such as the Pennsylvania firefly (''Photuris pennsylvanica''), state insect of Pennsylvania. They are among the "flashing" (as opposed to continuous-glow) 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.Stanger-Hall, Kathrin F.; Lloyd, James E. & Hillis, David M.

Lampyridae
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. The type species is '' Lampyris noctiluca'', the common glow-worm of Europe. 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 to trap their males as prey. Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. Although all known fireflies glow as larvae, only some species produce light in their adult stage, and the location o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rover Fireflies
The rover fireflies (''Photinus'') are a genus of fireflies (family Lampyridae). They are the type genus of tribe Photinini in subfamily Lampyrinae. This genus contains, for example, the common eastern firefly (''P. pyralis''), the most common species of firefly in North America. Male ''Photinus'' beetles emit a flashing light pattern to signal for females. Illegitimate receivers, such as female ''Photuris'' beetles, identify these signals and use them to locate the male ''Photinus'', attract them with deceptive signals, and eat them. An important study on the diversity of species in the USA and their visual communication was by Lloyd (1966) Etymology ''Photinus'' is from the Greek word for shining or bright. Systematics The closest living relative of the rover fireflies is not yet determined with certainty. In morphology (biology), morphology, they resemble their predators, the Photurinae, but they are quite certainly not at all closely related as fireflies go. Rather, th ...

Photuris Lucicrescens
''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. Description ''P. lucicrescens'' is a large firefly, with adults measuring 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. Etymology ''Photuris'' has its origins in the Greek words for light, "ph ...

Femme Fatale
A ( , ; ), sometimes called a maneater, Mata Hari, or vamp, is a stock character of a mysterious, beautiful, and Seduction, seductive woman whose charms ensnare her lovers, often leading them into compromising, deadly traps. She is an archetype of literature and art. Her ability to enchant, entice and hypnotize her victim with a spell was in the earliest stories seen as verging on supernatural; hence, the ''femme fatale'' today is still often described as having a power akin to an enchantress, seductress, witch, having power over men. Femmes fatales are typically villainous, or at least morally ambiguous, and always associated with a sense of wiktionary:mystification, mystification, and unease.Mary Ann Doane, ''Femme Fatales'' (1991) pp. 1–2 The term originates from the French phrase '':fr:Femme fatale, femme fatale'', which means 'deadly woman' or 'lethal woman'. A ''femme fatale'' tries to achieve her hidden purpose by using feminine wiles such as beauty, charm, or sexual al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photuris
''Photuris'' is a genus of firefly, fireflies (beetles of the family (biology), family Lampyridae). 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 matesbut ''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 adaptation, adapted to those of their prey, mainly unrelated Lampyrinae, such as ''Photinus (beetle), Photinus'' (rover fireflies) or ''Pyractomena''. Species At least 64 species are currently recognized, all restricted to temperate North America. They mainly occur from the East Coast to Texas.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is Cladogram#Homoplasies, homoplasy. The recurrent evolution of flight is a classic example, as flying pterygota, insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas ''homology (biology), homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach t ... of freshwater fish.
