Pyrearinus candelarius is a species of click beetle (family Elateridae).
The basic coloration is dark brown. The eyes are large and the pronotum is yellowish or pale brown, with a blackish area in the middle and small backward-pointing teeth. These beetles are bioluminescent by means of two luminescent light organs at the posterior corners of the prothorax, emitting green light, and a large abdominal area on the first segment, emitting yellow light. They do not flash, they emit light continuously. Eggs and pupae are bioluminescent too.
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus Vibrio; in others, it is autogenic, produced by the animals themselves.
Luciferin is a generic term for the light-emitting compound found in organisms that generate bioluminescence. Luciferins typically undergo an enzyme-catalyzed reaction with molecular oxygen. The resulting transformation, which usually involves breaking off a molecular fragment, produces an excited state intermediate that emits light upon decaying to its ground state. The term may refer to molecules that are substrates for both luciferases and photoproteins.
Elateridae or click beetles are a 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 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. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself. There are about 9300 known species worldwide, and 965 valid species in North America.
The beetle family Phengodidae is known also as glowworm beetles, whose larvae are known as glowworms. The females and larvae have bioluminescent organs. They occur throughout the New World from extreme southern Canada to Chile, numbering over 250 species in total. The recently recognized members of the Phengodidae, the Cydistinae, are found in Western Asia. The family Rhagophthalmidae, an Old World group, used to be included in the Phengodidae.
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 Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives. It consists of about 25,000 species.
Pyrophorus is a genus of click beetle. 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. 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.
A photocyte is a cell that specializes in catalyzing enzymes to produce light (bioluminescence). Photocytes typically occur in select layers of epithelial tissue, functioning singly or in a group, or as part of a larger apparatus. They contain special structures called photocyte granules. These specialized cells are found in a range of multicellular animals including ctenophora, coelenterates (cnidaria), annelids, arthropoda and fishes. Although some fungi are bioluminescent, they do not have such specialized cells.
Lampyris noctiluca, the common glow-worm of Europe, is the type species of beetle in the genus Lampyris and the family Lampyridae.
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.
Pyrophorus noctilucus, common name headlight elater, is a species of click beetle.
Pyrophorus punctatissimus is a species of click beetle.
Pyrophorus tuberculifer is a species of click beetle.
Pyrearinus is a genus of click beetle.
Diplocardia longa is a species of earthworm native to North America. It was first described by the American zoologist John Percy Moore in 1904. The type locality is Hawkinsville, Georgia. This worm has bioluminescent properties; its body fluids and the sticky slime it exudes when stimulated emit a bluish glow.
Oculogryphus chenghoiyanae, is a species of firefly beetles belonging to the family Lampyridae. It is endemic to Hong Kong.
Ignelater is a genus of click beetle. They are one of several genera in the tribe Pyrophorini, all of which are bioluminescent. Most of the species were formerly in the genus Pyrophorus.
The Pyrophorini are a New World taxonomic tribe within the Elateridae subfamily Agrypninae. Pyrophorini is a tribe of bioluminescent beetles, and includes such genera as Pyrophorus and Ignelater.
Campyloxenus is a bioluminescent genus of click beetles in the family Elateridae, and is the sole member of the subfamily Campyloxeninae. There is one described species in Campyloxenus, Campyloxenus pyrothorax.
Sinopyrophorus is a genus of bioluminescent hard-bodied clicking beetles in the superfamily Elateroidea, and is the sole member of the recently recognized family Sinopyrophoridae. The genus currently contains a single species, Sinopyrophorus schimmeli, which was described in 2019 from the subtropical evergreen broadleaf forests of western Yunnan, China.
