Coleoptera
Scientific names. The scientific name of a species is governed by internationally accepted rules that determine what the name is and insure that each species has only one. Thus scientific names are the same in every locality and in every language. Each scientific name of a species is two words (a binomen) the first is the name of the genus to which the species is assigned, the second is the specific name. The genus name is capitalized, the specific name is not, and both are printed in italics. Beetles are by far the largest order of insects, with 350,000–400,000 species in four suborders (Adephaga, Archostemata, Myxophaga, and Polyphaga), making up about 40% of all insect species described, and about 30% of all animals. For example, the known beetle diversity of Australia is estimated at 23,000 species in 3265 genera and 121 families. This is slightly lower than reported for North America, a land mass of similar size with 25,160 species in 3526 genera and 129 families. The word coleoptera is from the Greek κολεός, koleos, meaning sheath; and πτερόν, pteron, meaning wing, thus sheathed wing, because most beetles have two pairs of wings, the front pair, the  elytra , being hardened and thickened into a shell-like protection for the rear pair and the beetle's abdomen. For example, the known beetle diversity of Australia is estimated at 23,000 species in 3265 genera and 121 families. This is slightly lower than reported for North America, a land mass of similar size with 25,160 species in 3526 genera and 129 families. Such a name is called a binomial name (which may be shortened to just binomial), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Hi,   First of all I have to say that, I'm just a Beetle lover freak. Then I'll say it depends on, because every species have a specific scientific name and there are some … common names for famous families, subfamilies, species or something and so on, like rhinoceros beetles or rhino beetle. There are many different species of large black beetles each with their own unique scientific name. Using a field guide or speaking to an entomologist would be places to start … identifying a beetle. 2 people found this useful. About 40% of all described insect species are beetles (about 400,000 species), and new species are discovered frequently. Some estimates put the total number of species, described and undescribed, at as high as 100 million, but a figure of one million is more widely accepted. For example, the known beetle diversity of Australia is estimated at 23,000 species in 3265 genera and 121 families. This is slightly lower than reported for North America, a land mass of similar size with 25,160 species in 3526 genera and 129 families. Common Name: June beetle (June bug) Scientific Name: Phyllophaga sp. Order: Coleoptera Description: Adult beetles, commonly referred to as May beetles or June bugs are to 5/8 inches long, and reddish brown. There are more than 100 species of scarab beetles from several genera (e.g.,Cyclocephala, Phyllophaga and others) in Texas that are considered to be white grubs, May beetles and June bugs. However, the most common is Phyllophaga crinita. They do not fly. Predators of ground beetles are the same as those of other beetles, including toads, small snakes, shrews, and birds. This beetle is just one of many species which get the name Common Black Ground Beetle.. Many of the different species are very similar. This ground beetle can grow a little over half an inch long. It is nearly all black with some dark reddish-brown coloring on antennae and legs. Many grooves run lengthwise down the beetle's wings.
