Lampyridae (firefly) are a family of insects which contain ca. 2,000 species. Not all species of fireflies can transmit light signals. Fireflies can meet all continents except Antarctica continent.
Highest intensity light is produced by the species Photinus pyralis, which lives in Central America and South America.
Caves in Australia and New Zealand building ceiling light tubes of mucus that may have silky 1m. These tubes resemble drops of glue or with a string of pearls, are of great beauty. They build in their light dark places as the insects they eat. These tubes have become silky attraction even if they do not like fireflies.
In some species the females have no wings, they must shine to attract males.
Also called worms shining.
Most adults do not hransec no, no mouth and no digestive system, instead soil-dwelling larvae prey on snails, worms and caterpillars.
Fireflies inject paralyzing prey with digestive enzymes that break down tissue and then suck the fluids within them.
Some firefly larvae eat mites or pollen particles.
Usually fireflies are black or brown and have elongated bodies. If you've seen a firefly in your hand as you have quite fragile bodies unlike other types of cockroaches.
It is necessary to be kept in hand with care because they crush easily. Viewed from above, fireflies head seems to have protected large shield, a family feature fireflies. In most fireflies last two or three abdominal segments are modified as organs generating light.
Firefly larvae live in dark, damp places - in the soil under the bark of trees, even in swampy areas. Like adults, larvae of fireflies produce light. In fact fireflies produce light at all stages.
The light produced is a bio luminescence that is accomplished by an enzyme called luciferase acid, triphosphoric acid (ATP) in the presence of oxygen, the oxidation releases enegie the form of light in a proportion of 95% with a very low percentage of heat.
So far not managed with current technology to produce a high yield so light. Light produced by fireflies reckoned size is 1,000 times stronger than the light produced by a candle.
The larvae have black or brown velvety. Larvae and adult females have a length of only 25mm and a male has a length of only 15mm. Their weight, whether adults or larvae is several grams. They live in colonies with other firefly larvae and cunt very strict with the territory. In Central Europe live three species of fireflies:
- Lamprohiza splendidula
- Lampyris noctiluca
- Phosphaenus hemipterus
Fireflies lay eggs in moist soil. These eggs hatch after a few weeks become larvae. They remain in the larval stage for several years before becoming pupae spring. In a period between 10 days and a few weeks out adults living just enough to lay eggs.
Fireflies are most known for their adaptation of the most interesting - emit light. Male fireflies emit light in specific patterns abdomen species hoping to attract the attention of females hiding in the grass. The female will signal interested in the same way as the male helping to find in the dark.
Some women use this behavior more sinister purposes. Females of some species mimicking patterns of other species lit luring males of other species.
When the male arrives, he will eat it. Male fireflies are equipped with protective chemicals that consumed by predatory females will help them better protect their eggs. Most women are not cannibals.
Did you know that:
The light emitted by fireflies emit less heat
Firefly light emitted is 1000 times brighter than a candle.
American entomologists surprisingly found that each male firefly has prepared for his future partner a gift that consists of sperm cells with a portion of ... food.
