Oecanthus Niveus
''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. Identification Adult ''O. niveus'' are typically 13-16mm in length. They are a pale green with a pale orange head, and feature a dark streak running medially along the pronotum. On top of the head is an orange cap. Habitat ''O. niveus'' can be found on broad-leaved trees, herbaceous plants, shrubbery, and in man-made orchards. Song Like other members of the genus ''Oecanthus'', the song of the male narrow-winged tree cricket varies in pitch and beats per minute depending the temperature, with warmer temperatures resulting in more rapid calling at a higher pitch. At 25°C, the pulse rate averages 71/sec at a frequency o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles De Geer
Charles De Geer (30 January 1720 – 7 March 1778) was an entomology, entomologist, industrialist, civil servant and book collecting, book collector. He is sometimes referred to as Charles the Entomologist, to distinguish him from other relatives with the same name. Charles De Geer came from a prominent Swedish-Dutch family. Born in Sweden, he spent most of his childhood and youth in the Dutch Republic. At the age of 18 he moved back to Sweden and would spend the rest of his life there. Upon his return to Sweden, he took over the management of the ironworks of Lövstabruk. He was a successful businessman and with time became one of the richest men in Sweden, head of an early industry employing around 3,000 people. He had a successful civic career, became Marshal of the Court (Sweden), Marshal of the Court and was elevated to the rank of ''Freiherr#Swedish_and_Danish–Norwegian_title, friherre'' (baron) in 1773. De Geer had developed an interest in natural history and particula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Cricket
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gryllidae
The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years (''e.g.'' ImmsImms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp.): taxa such as the tree crickets, spider-crickets and their allies, sword-tail crickets, wood or ground crickets and scaly crickets have been moved or elevated to family level. The type genus is '' Gryllus'' and the first use of the family name "Gryllidae" was by Francis Walker. They have a worldwide distribution (except Antarctica). The most familiar field crickets ( Gryllinae) are characteristically robust brown or black insects; the largest members of the family are the -long bull crickets ('' Brachytrupes'') which excavate burrows a metre or more deep. Subfamilies The family is divided into these subfamily grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insects Of The Caribbean
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues.

Orthoptera Of North America
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera). Etymology The name is derived from the Greek meaning " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxa Named By Charles De Geer
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
