Tree Cricket
Tree crickets are insects of the Order (biology), order Orthoptera. These cricket (insect), crickets are in the subfamily Oecanthinae of the Family (biology), family Gryllidae. Description Tree crickets as well as most other crickets have two pairs of wings. The fore wings are located closer to the head and are hard and leathery in appearance. The hind wings are located aft of the fore wings and are the wings it uses for flight. When the cricket is not in flight the fore wings fold back to cover the hind wings. The bodies of tree crickets are long and skinny with a coloration that matches their habitat. They have large powerful legs used for jumping. Their heads contain two antennae which can sense both touch and odor and compound eyes which are inherent in all Orthoptera. Distribution and habitat They live in trees and shrubs, for which they are well camouflaged. These crickets are nocturnal and can be found on every continent except Antarctica. In Europe, tree crickets hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oecanthus Fultoni
''Oecanthus fultoni'', also known as the snowy tree cricket, or thermometer cricket, is a species of tree cricket from North America. It feeds on leaves but also damages fruit. The chirp of this species is often dubbed onto sound tracks of films and television shows to depict a quiet summer's night. The rate of chirp varies depending on the heat of the environment, allowing a listener to estimate the temperature. Etymology ''Oecanthus fultonis common name of the thermometer cricket is derived from a relationship between the rate of its chirps and the temperature. An estimate of the temperature in Fahrenheit can be made by adding 40 to the number of chirps made in 15 seconds. Before 1960, the name '' Oecanthus niveus'' was wrongly applied to this species. ''Oecanthus fultoni'' was named in honor of Bentley Ball Fulton (1880–1960), an American entomologist who laid the principal groundwork on North American cricket classification. Description The species is long and is li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Eye
A compound eye is a visual organ found in arthropods such as insects and crustaceans. It may consist of thousands of ommatidia, which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color. The image perceived by this arthropod eye is a combination of inputs from the numerous ommatidia, which are oriented to point in slightly different directions. Compared with single-aperture eyes, compound eyes have poor image resolution; however, they possess a very large view angle and the ability to detect fast movement and, in some cases, the polarization of light. Because a compound eye is made up of a collection of ommatidia, each with its own lens, light will enter each ommatidium instead of using a single entrance point. The individual light receptors behind each lens are then turned on and off due to a series of changes in the light intensity during movement or when an object in moving, creating a flic ...

Tribe (taxonomy)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
