When was Photuris pennsylvanica created?
Photuris pennsylvanica was created in 1774.
What is Photuris frontalis?
Photuris frontalis is a species of fireflies that emits one flash every second. This kind of flash can be used to attract mates of this species.
What is Photuris hebes?
Photuris hebes is a species of fireflies that emits one flash every two seconds. This kind of flash can be used to attract mates of this species.
Is a firefly a arachnid?
No, a firefly is not an arachnid, it is an insect. There is different kinds of fireflies, like Black fireflies, Eastern fireflies, Photuris species fireflies, etc.
What is the scientific name of candle?
Reformulate your question - 1 Lumen = the amount of light that a standard candle produces in relation to human sight.. theres an equation but it seems not to include the individuals capacity to see ;)
What is the scientific name of a lighting bug?
There is an entire family called by that common name, so you'd have to be more specific if you wanted to know a particular... well, species.The name for the family is Lampyridae.The most common of the species called "lightning bugs" in the US is probably Photinus pyralis. Another species is Photuris pennsylvanica.
What lightning bugs eat?
In the larval stage, which comprises most of their lifespan, lightning bugs eat slugs, snails, and earthworms.As adults, many fireflies don't eat anything at all—they're only adults for a few weeks, so they mostly just procreate and die. However, females from the Photuris group are a notable exception. These "femme fatale" fireflies lure in males from other groups with enticing flashes and then, as the nickname suggests, eat them. Think about that next time you're oohing and ahhing over them in the backyard.

State animal of Pennsylvania?
The firefly (commonly called "lightning bug") is Pennsylvania's state insect, as of April 10, 1974. As of December 5, 1988, the species "Photuris pennsylvanica, De Geer" is the official state insect.Sources: www.pa.gov > About Pennsylvaniahttp://www.legis.state.pa.us/WU01/VC/visitor_info/quiz2/insect.htm
Which insect uses bioluminescence for mating?
Click beetles and fireflies are both bio luminescent. Click beetles are equipped with two menacing "false eye-spots" on the thorax, and many are more than 1-1/2 inches in length. Tropical relatives of the big-eyed click beetle are called fire beetles and have bioluminescent eye-spots. One, Pyrophorus luminosa, produces "cold light" that is green and red, and is as bright as that of the more familiar fireflies. Its larvae, called glow-worms, also produce light.
What do firefly eat?
bugs and flowers
When do fireflies glow?
Light production in fireflies is due to a chemical reaction that occurs in specialized light-emitting organs, usually on the lower abdomen. The enzyme luciferase acts on luciferin in this organ to stimulate light emission. Genes coding for these substances have been inserted into many different organisms (see Luciferase - Applications). Luciferase is also used in forensics, and the enzyme has medical uses. For adult beetles, it is primarily used to locate other individuals of the same species for reproduction. Many species, especially in the genus Photinus, are distinguished by the unique courtship flash patterns emitted by flying males in search of females. Photinus females generally do not fly, but give a flash response to males of their own species. Bioluminescence is a very efficient process. Some 90% of the energy a firefly uses to create light is actually converted into visible light. By comparison, an incandescent electric bulb can convert only 10 percent of total energy used into visible light, and the remainder is emitted as heat. Tropical fireflies, particularly in Southeast Asia (Thailand and Malaysia), routinely synchronize their flashes among large groups, a startling example of spontaneous biological order. This phenomenon occurs through the night along river banks in the Malaysian jungles every day of the year. Current hypotheses about the causes of this behavior involve diet, social interaction, and altitude. In the United States, one of the most famous sightings of fireflies blinking in unison occurred near Elkmont, Tennessee in the Great Smoky Mountains during the second week of June 2005. Congaree National Park in South Carolina is another host to the phenomenon. Female Photuris fireflies are known for mimicking the mating flashes of other fireflies for the sole purpose of predation. Target males are attracted to what appears to be a suitable mate, and are then eaten. For this reason the Photuris female is sometimes referred to as "femme fatale". Many fireflies do not produce light. Usually these species are diurnal, or day-flying, such as those in the genus Ellychnia. A few diurnal fireflies that primarily inhabit shadowy places, such as beneath tall plants or trees, are luminescent. One such genus is Lucidota. All fireflies glow as larvae. Bioluminescence serves a different function in lampyrid larvae than it does in adults. It appears to be a warning signal to predators, since many firefly larvae contain chemicals that are distasteful or toxic.
