Oberea Tripunctata
''Oberea tripunctata'', the dogwood twig borer, is a species of longhorn beetle that is a widespread pest that attacks dogwood trees. Morphology Dogwood twig borer adults have slender, elongated bodies like many other beetles of the genus ''Oberea''. They are between 10 and 15 millimeters long and 3 millimeters wide. The head is dark to black and there are three prominent black spots arranged in a triangle on the beetles' thorax. The wing covers are a yellowish tan. There is a narrow black line on the inner edge and a broader, darker line on the outer wing on the lateral margin. There are also two distinct dots right behind the beetle's head. The larvae of dogwood twig borers, in their final phase, are yellowish, legless and about 19 millimeters long. Diet The dogwood twig borer is distributed in the United States of America wherever there are flowering dogwood trees. They are adaptable and although the bulk of a dogwood twig borer's diet is obtained from flowering dogwood tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nils Samuel Swederus
Nils Samuel Swederus also Svederus (24 August 1751 – 1833) was a Swedish naturalist. His parents were Sigtuna Magnus Svederus and Anna Maria Christiernin. Nils Samuel Swederus studied theology and other disciplines at the University of Uppsala. He was ordained in 1780 and became a ''hofpredikanten'' or Royal Court chaplain in 1782. From 1784 to 1786 he made scientific trips to several European countries—to England, France, Belgium and the Netherlands. In 1789 he became Vicar of Nasby and Ervalla parishes and dean of Fellingsbro. Nils Samuel Swederus was especially interested in entomology and was elected to membership of several learned societies in Sweden and abroad. These included the Royal Swedish Academy of Sciences. He was married to Anna Margareta Oberg. Works *1787 Fortsättning af Beskrifningen på 50 nya Species af Insecter. ''Kongliga Vetenskaps Academiens Nya Handlingar'' 8 (10–12): 276–290.

Longhorn Beetle
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short (e.g., '' Neandra brunnea'') and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns. Description Other than the typical long antennal length, the most consistently distinctive feature of the family is that the antennal sockets are located on low tubercles on the face; other beetles with long antennae lack these tubercles, and cerambycids with short antennae still possess them. They otherwise vary greatly in size, shap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dogwood
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''(Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood ''Cornus kous ...

United States Of America
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo ...

Girdling
Girdling, also called ring-barking, is the complete removal of the Bark (botany), bark (consisting of cork cambium or "phellogen", phloem, cambium and sometimes going into the xylem) from around the entire circumference of either a branch or trunk (botany), trunk of a woody plant. Girdling results in the death of the area above the girdle over time. A branch completely girdled will fail and when the main trunk of a tree is girdled, the entire tree will die, if it cannot regrow from above to bridge the wound. Human practices of girdling include forestry, horticulture, and vandalism. Foresters use the practice of girdling to thin forests. Animals such as rodents will girdle trees by feeding on outer bark, often during winter under snow. Girdling can also be caused by herbivorous mammals feeding on plant bark and by birds and insects, both of which can effectively girdle a tree by boring rows of adjacent holes. Orchardists use girdling as a cultural technique to yield larger fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synanthedon Scitula
''Synanthedon scitula'', the dogwood borer or pecan borer, is a moth that is a pest of many plants including the dogwood and pecan. It is notorious due to the severity of damage it can cause and its widespread geographical distribution. Description and ecology Eggs ''Synanthedon scitula'' eggs are a light chestnut brown color and are 0.4 to 0.6 millimeters across. They are marked with a hexagonal pattern of lines. The eggs are laid singly by the mother and take 8–9 days to hatch. Larvae ''Synanthedon scitula'' larvae are cream colored with a red head. They pass through six instars ranging in length from 1 millimeter to 15 millimeters or more at the last instar. Soon after hatching they burrow into the burrknot tissue or areas around bark scales. As the dogwood borer larvae feed red frass is pushed to the surface. It collects and is pushed to the surface and held together by silk. Larvae overwinter in their feeding tunnel, and resume eating whenever the temperature exceeds 45 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little actual direct contradiction on the practical realities. One glossary from the early twentieth century speaks of "...excreme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beetles Described In 1787
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
