Pyrophorus (beetle)
''Pyrophorus'' (also known as fire beetles) is a genus of click beetle (family Elateridae). They are one of several genera in the tribe Pyrophorini, all of which are bioluminescent. Their bioluminescence is similar to that of another group of beetles, the fireflies, although click beetles do not flash, but remain constantly glowing (though they can control the intensity; for example, they become brighter when touched by a potential predator). They have two luminescent spots at the posterior corners of the pronotum, and another brighter light organ on the most-anterior surface of the ventral abdomen. This light organ is even brighter and can only be seen when in flight. Bioluminescent click beetles are found throughout tropical, subtropical and temperate America. Species from Texas, Florida, Puerto Rico, and Cuba are now in different genera in the tribe Pyrophorini, such as '' Deilelater'' and ''Ignelater''. Adult ''Pyrophorus'' beetles feed on pollen and sometimes small insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Karl Wilhelm Illiger
Johann Karl Wilhelm Illiger (19 November 1775 – 10 May 1813) was a German entomologist and zoologist. Illiger was the son of a merchant in Braunschweig. He studied under the entomologist Johann Christian Ludwig Hellwig, Johann Hellwig, and later worked on the zoological collections of Johann Centurius Hoffmannsegg. Illiger was professor and director of the "zoological museum" (which is the Natural History Museum, Berlin, Natural History Museum of Berlin in the present day) from its formation in 1810 until his death. He was the author of ''Prodromus systematis mammalium et avium'' (1811), which was an overhaul of the Carl Linnaeus, Linnaean system. It was a major influence on the adoption of the concept of the Family (biology), family. He also edited the ''Magazin für Insektenkunde'', widely known as "Illiger's Magazine". In 1811 he introduced the taxonomic order Proboscidea for elephants, the American Mastodon, American mastodon and the woolly mammoth. He also described the ...

Pyrophorus Nyctophanus
''Pyrophorus nyctophanus'' (=''fire-bearing night-shiner''), aka headlight beetle or carbunco, is a species of click beetle that occurs on the cerrado of Brazil. Its luminescent larvae are either soil-dwelling or found in tunnels in the outer layers of termite mounds, and are active predators of other insects during summer nights when their regulated glow acts as a lure to their prey. The adult beetles, though, are phytophagous, feeding on decomposing plant matter and exudates, and are attracted to artificial light. Pupae of this genus also luminesce. "Headlight beetles are large click beetles notable among click beetles in their unique ability to produce light. An intense glow emanates from two round luminescent organs on the prothorax and a broad area on the underside of the first abdominal segment. In flight both sexes produce a brilliant blue-green streak of light that dazzles the onlooker." - Charles Leonard Hogue Some 26 species of ''Pyrophorus'' are found from southern Me ...

Pyrophorus Ignigenus
A substance is pyrophoric (from grc-gre, πυροφόρος, , 'fire-bearing') if it ignites spontaneously in air at or below (for gases) or within 5 minutes after coming into contact with air (for liquids and solids). Examples are organolithium compounds and triethylborane. Pyrophoric materials are often water-reactive as well and will ignite when they contact water or humid air. They can be handled safely in atmospheres of argon or (with a few exceptions) nitrogen. Class D fire extinguishers are designated for use in fires involving pyrophoric materials. A related concept is hypergolicity, in which two compounds spontaneously ignite when mixed. Uses The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. The sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous m ...
