Ignelater Luminosus
''Ignelater luminosus'' is a bioluminescent species of click beetle native to the island of Puerto Rico, one of several Caribbean species in the genus ''Ignelater'' that are known as cucubanos. Cucubanos are often confused with fireflies, which are in a different family (Lampyridae), but they emit light from the thorax, unlike true fireflies. Their paired prothorax light organs and single light organ on the anterior surface of the abdomen gives the appearance of two "headlights" and one "backlight", which it can turn off independently. Because light pollution interferes with their reproduction, they prefer rural areas without much development.. Prof. of EntomologyPurdue University Retrieved April 29, 2011. Locations known to be its habitat are the rural areas and outskirts of the city of Adjuntas Adjuntas () is a small mountainside Adjuntas barrio-pueblo, town and Municipalities of Puerto Rico, municipality in Puerto Rico located in the central midwestern portion of the island ...

Pyrophorini
The Pyrophorini are a New World taxonomic tribe within the Elateridae (click beetle) subfamily Agrypninae.Kundrata R, Kubaczkova M, Prosvirov AS, Douglas HB, Fojtikova A, Costa C, Bousquet Y, Alonso-Zarazaga MA, Bouchard P (2019) World catalogue of the genus-group names in Elateridae (Insecta, Coleoptera). Part I: Agrypninae, Campyloxeninae, Hemiopinae, Lissominae, Oestodinae, Parablacinae, Physodactylinae, Pityobiinae, Subprotelaterinae, Tetralobinae. ZooKeys 839: 83–154. https://doi.org/10.3897/zookeys.839.33279 Pyrophorini is a tribe of bioluminescent beetles, and includes such genera as '' Pyrophorus'' and ''Ignelater''. It is believed to be monophyletic. The tribe Anaissini is very closely related to the Pyrophorini (it includes species formerly placed in Pyrophorini); the latter is exclusively bioluminescent, while the former has only some species that are known to be bioluminescent. Another bioluminescent lineage is '' Campyloxenus pyrothorax'' (from Chile) in the rel ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Click Beetle
Elateridae or click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae and Eucnemidae, which are also capable of clicking) are a family (biology), family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815. They are a cosmopolitan distribution, cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few other families of Elateroidea in which a few members have the same mechanism, but most elaterid subfamilies can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" that can bounce the beetle into the air. The evolutionary purpose of this click is debated: hypotheses include that the clicking noise deters predators or is used for communication, or that the click may allow the beetle to "pop" out of the subtrate in which i ...

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 insects, s ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sclerotized
Sclerosis (also sclerosus in the Latin names of a few disorders) is a hardening of tissue and other anatomical features. It may refer to: * Sclerosis (medicine), a hardening of tissue * in zoology, a process which forms sclerites, a hardened exoskeleton * in botany, a process which hardens plant tissue by adding fibers and sclereids, resulting in sclerenchyma * in economics, eurosclerosis Eurosclerosis (German: ''Eurosklerose'') is a term coined by German economist Herbert Giersch in the 1970s, to describe a pattern of economic stagnation in Europe that may have resulted from government over-regulation and overly generous social be ... {{disambig ar:تَصلُب ca:Esclerosi mk:Склероза pl:Stwardnienie pt:Esclerose fi:Skleroosi sv:Skleros zh:硬化 ...

Spiral
In mathematics, a spiral is a curve which emanates from a point, moving further away as it revolves around the point. It is a subtype of whorled patterns, a broad group that also includes concentric objects. Two-dimensional A two-dimensional, or plane, spiral may be easily described using polar coordinates, where the radius r is a monotonic continuous function of angle \varphi: * r=r(\varphi)\; . The circle would be regarded as a degenerate case (the function not being strictly monotonic, but rather constant). In ''x-y-coordinates'' the curve has the parametric representation: * x=r(\varphi)\cos\varphi \ ,\qquad y=r(\varphi)\sin\varphi\; . Examples Some of the most important sorts of two-dimensional spirals include: * The Archimedean spiral: r=a \varphi * The hyperbolic spiral: r = a/ \varphi * Fermat's spiral: r= a\varphi^ * The lituus: r = a\varphi^ * The logarithmic spiral: r=ae^ * The Cornu spiral or ''clothoid'' * The Fibonacci spiral and golden spiral * ...

Oviduct
The oviduct in vertebrates is the passageway from an ovary. In human females, this is more usually known as the fallopian tube. The eggs travel along the oviduct. These eggs will either be fertilized by spermatozoa to become a zygote, or will degenerate in the body. Normally, these are paired structures, but in birds and some cartilaginous fishes, one or the other side fails to develop (together with the corresponding ovary), and only one functional oviduct can be found. Except in teleosts, the oviduct is not directly in contact with the ovary. Instead, the most anterior portion ends in a funnel-shaped structure called the infundibulum, which collects eggs as they are released by the ovary into the body cavity. The only female vertebrates to lack oviducts are the jawless fishes. In these species, the single fused ovary releases eggs directly into the body cavity. The fish eventually extrudes the eggs through a small genital pore towards the rear of the body. Fish and amphibia ...
