summer evening, creek thesaharai arselycoveredwithvarioustypesofvegetationrangingfromgra es, forest, common have YiZhanZhan hung in the air of little lights, like dew, and strove with stars like selvesor lovers lantern night. If you use small nets, the "little lights" cover, then you can see it is a small scale BVB beetles. Because of its abdomen end can emit fluorescent dots, people give it up an image's name, the fireflies. Br> <<> fireflies in Chinese family belongs to coleoptera insects, hotaru division. World known they distant relatives or about than 2100, our country has recorded 76 species. General fireflies snakeholes a few millimeters, the biggest ending 17 millimeter above. Fireflies is a kind of magic and beauty of insects. Slender slightly flat body with glaucous burnish, trimmed backplane relatively flat, often cover their heads, and on his head with a pair of small teeth feelers are divided into 11 subclauses. Three pairs of fine, good at crawling feet. The male of finned scabbard developed after the wings, like, at ordinary times of variable-speed sectoral before flying wings, only when it extended, The female of finned short or no wings. Some groups have social gender, need explanation is not fireflies secco all species can shine. Fireflies life, after eggs and larvae, pupa, adult four different insect configuration, belong to completely abnormal condition of insects. Br>> <

fireflies body of fluorescent element is not inexhaustible, 135 so they constantly repeatedly luminescence, energy is come from? The original energy comes from adenosine triphosphate (ATP), it is referred to as all organisms supply energy substance. Fireflies body with this energy, not only can incessantly shine, and brightness are stronger. Only luminous structure still cannot shine, have nerve system adjustment disposal. If do an experiment, will fireflies glow mechanism, head resection will lose action. Female insect an abdominal countdown 2, 3 quarter entire sections can shine, and look like for the wide band, and small d-type luminescence, it only formation in relationship two side, from the reverse side also can see. Male worm only can shine, and abdominal small female insect abdomen is same, also shows two small plaque-forming light. Br> <<> eggs and larvae, br chrysalis can shine. Eggs in martina is cannot shine, just near the mercury, from eggs shell outside visible 2 points of light. Experiments have shown it is in the egg shell activities within the larva, therefore, is actually caused by has already formed the larvae of hair of light. Larvae belly bottom end verse 2 visible lighter, but can only hair two points from the back, it is visible. Change pupa 4-5 days, pupa abdomen end on each side, but there is a visible spot in sediment do chrysalis cocoon chamber, so its luminescence is not visible. Br> <<> fireflies glow br efficiency is very high, almost all the chemical energy can be transformed into visible light, and for the modern electric light source efficiency several times to dozens of times. Because light is coming from body chemicals, therefore, fireflies came out light is bright but no heat, also do not produce a magnetic field, people call this kind of light as "cold". Because the light of fireflies without radiate heat, physicists think it is very ideal lamplight, because general things when luminescence, also want to fever, such as lit candles. And as electric light bulb also open - after hot. But people do not need lamplight fever, if can create like fireflies as fever of light that would be ideal. Thirty years ago, people simulated fireflies glow principle to create a fluorescent lamp (fluorescent lamps), base - this met such a request. Br>> <
