FIREFLIES

At this time i want to tell you reader about "Firefly". Do you know about this beautiful looking creature? do you know why they can produce light from their body? if you know, that's cool but, if you dont you must stick to this disscussion, and i will tell you about it's scientific classification ; ).

The Lampyridae are a family of insects in the beetle order Coleoptera with over 2,000 described species. They are soft-bodied beetles that are commonly called fireflies or lightning bugs for their conspicuous use of bioluminescence during twilight to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometers. Some species such as the dimly glowing "blue ghost" of the Eastern US are commonly thought to emit blue light (<490 nanometers), though this is a false perception of their truly green emission light due to the Purkinje effect.

Fireflies are found in temperate and tropical climates. Many are found in marshes or in wet, wooded areas where their larvae have abundant sources of food. Some species are called "glowworms" in Eurasia and elsewhere. While all known fireflies glow, only some adults produce light and the location of the light organ varies among species and between sexes of the same species. The form of the insect which emits light varies from species to species (for example, in the glow worm found in the UK, Lampyris noctiluca, it is the female that is most easily noticed. In the Americas, "glow worm" also refers to the closely related family Phengodidae. In New Zealand and Australia the term "glow worm" is in use for the luminescent larvae of the fungus gnat Arachnocampa. In many species of fireflies, both male and female fireflies have the ability to fly, but in some species, the females are flightless

Light production in fireflies is due to a type of chemical reaction called bioluminescence. This process occurs in specialized light-emitting organs, usually on a firefly's lower abdomen. The enzyme luciferase acts on the luciferin, in the presence of magnesium ions, ATP, and oxygen to produce light. Gene coding for these substances has been inserted into many different organisms (see Luciferase – Applications). The genetics of firefly bioluminescence, focusing on luciferase, has been reviewed by John Day. Firefly luciferase is used in forensics, and the enzyme has medical uses – in particular, for detecting the presence of ATP or magnesium. All fireflies glow as larvae. In lampyrid larvae, bioluminescence serves a function that is different from that served in adults. It appears to be a warning signal to predators, since many firefly larvae contain chemicals that are distasteful or toxic.

Photic emission in the adult beetle was originally thought to be used for similar warning purposes, but it is now understood that its primary purpose is in mate selection. It has been shown that early larval bioluminescence was adopted in adult fireflies, and was repeatedly gained and lost before becoming fixed and retained as a mechanism of sexual communication in many species. Adult lampyrids have a variety of ways to communicate with mates in courtships: steady glows, flashing, and the use of chemical signals unrelated to photic systems. Chemical signals, or pheromones, are the ancestral form of sexual communication; this pre-dates the evolution of flash signaling in the lineage, and is retained today in diurnally-active species. Signals, whether photic or chemical, allow fireflies to identify mates of their own species. Flash signaling characteristics include differences in duration, timing, color, and repetition, and vary interspecifically and geographically. When flash signals are not sufficiently distinguished between species in a population, sexual selection encourages divergence of signaling patterns.

oh yeah and fireflies is also a music tittle sang by the owl city, its an old songs tho but it was nice, the song is so chill, you can check it if you want too ; ), but if you already know, you have a good taste of music believe me :D. That's my description about firefly, if you have something to say or anything just leave a comment.


questions

1. what is the other name for firefly?
2. what family did firefly from？
3. where usually firefly can be found?
4. how many described species are there?
5. what type of firefly that are flightless?
