Insects in the family Tettigoniidae are commonly called katydids, or bush crickets. They have previously been known as "long-horned grasshoppers". More than 8,000 species are known. Part of the suborder Ensifera, the Tettigoniidae are the only extant (living) family in the superfamily Tettigonioidea.
The Caelifera are a suborder of orthopteran insects. They include the grasshoppers and grasshopper-like insects, as well as other superfamilies classified with them: the ground-hoppers (Tetrigoidea) and pygmy mole crickets (Tridactyloidea). The latter should not be confused with the mole crickets (Gryllotalpidae), which belong to the other Orthopteran sub-order Ensifera.
Dolbear's law states the relationship between the air temperature and the rate at which crickets chirp. It was formulated by Amos Dolbear and published in 1897 in an article called "The Cricket as a Thermometer". Dolbear's observations on the relation between chirp rate and temperature were preceded by an 1881 report by Margarette W. Brooks, although this paper went unnoticed until after Dolbear's publication.
Tree crickets are insects of the order Orthoptera. These crickets are in the subfamily Oecanthinae of the family Gryllidae.
Oecanthus is a genus of cricket in subfamily Oecanthinae, the tree crickets.
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms, "crickets" were placed at the family level, but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets.
Oecanthus pellucens, common name Italian tree cricket, is a species of tree crickets belonging to the family Gryllidae, subfamily Oecanthinae.
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.
Oecanthus quadripunctatus is a "common tree cricket" in the subfamily Oecanthinae. A common name for O. quadripunctatus is four-spotted tree cricket. It is found in North America.
Oecanthus exclamationis is a "common tree cricket" in the subfamily Oecanthinae. A common name for O. exclamationis is Davis' tree cricket. It is found in North America.
Oecanthus latipennis is a "common tree cricket" in the subfamily Oecanthinae. A common name for O. latipennis is broad-winged tree cricket. It is found in North America.
Oecanthus varicornis, the different-horned tree cricket, is a species of tree cricket in the family Gryllidae. It was described by Francis Walker in 1869 and is found in Central and North America.
Oecanthus californicus, the western tree cricket, is a species of tree cricket in the family Gryllidae. It is found in North America.
Oecanthus rileyi, known generally as the Riley's tree cricket or pine tree cricket, is a species of tree cricket in the family Gryllidae. It is found in North America.
Oecanthus niveus, known generally as the narrow-winged tree cricket or snowy tree cricket, is a species of tree cricket in the family Gryllidae, which includes all crickets. First noted by Swedish Entomologist Charles de Geer in 1773 by a Pennsylvanian Specimen, it is found primarily in Eastern North America south of Canada, and also in the Caribbean.
Wētā is the common name for a group of about 100 insect species in the families Anostostomatidae and Rhaphidophoridae endemic to New Zealand. They are giant flightless crickets, and some are among the heaviest insects in the world. Generally nocturnal, most small species are carnivores and scavengers while the larger species are herbivorous. Although some endemic birds likely prey on them, wētā are disproportionately preyed upon by introduced mammals, and some species are now critically endangered.
Oecanthus forbesi, the Forbes' tree cricket, is a species of tree cricket in the family Gryllidae. It is found in North America.
Oecanthus dulcisonans is a species of cricket sparsely but widely distributed in the Mediterranean Basin and in the Middle East.
