Tenthredo Amoena
''Tenthredo amoena'' is a sawfly species belonging to the family Tenthredinidae (common sawflies). Distribution and habitat This species can be found in most of Europe. Description ''Tenthredo amoena'' can reach a length of about . These sawflies have a black body with yellowish markings and short antennae, that are about one and a half times the width of the head. The first antennal element is pure yellow. In the males the first, fifth and 7-8 tergites of the abdomen are yellow. The scutellum is often spotted with yellow. Wings show a pale brown color with a long brown pterostigma. In the females the apex of tibiae and tarsi are yellow with black markings. The thighs are pure black. This species is rather similar to ''Tenthredo distinguenda''. Biology The adults can be encountered from June through July feeding on nectar and pollen of flowers (especially on Apiaceae species). The larvae feed on leaves of ''Hypericum'' species, mainly of ''Hypericum perforatum'' and ''Hyper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pterostigma
The pterostigma (plural: pterostigmata) is a group of specialized cells in the outer insect wing, wings of insects, which are often thickened or coloured, and thus stand out from other cells. It is particularly noticeable in dragonfly, dragonflies, but present also in other insect groups, such as snakefly, snakeflies, hymenopterans, and megalopterans. Purpose The pterostigma, a heavier section of the wing than nearby sections, assists in gliding. Without the pterostigmata, self-exciting vibrations known as aeroelastic flutter, flutter would set in on the wing above a certain critical speed, making gliding impossible. Tests show that with the pterostigmata, the critical gliding speed is increased 10–25% on one species of dragonfly. Pseudopterostigma Some female damselfly, damselflies in the family Calopterygidae possess a ''pseudopterostigma''. This is similar in location on the wing to a true pterostigma but is crossed by veins and is only defined by its paler colour compared ...

Tenthredo Amoena Sawfly Larva On Klamath Weed (Hypericum Perforatum)
''Tenthredo'' (from the Greek ''tenthrēdōn'' "earth nesting wasp") is a genus of sawflies with more than 700 species of the family Tenthredinidae, subfamily Tenthredininae. It is of Holarctic distribution. Description Species of this genus are easily recognisable by their wasplike appearance although lacking the thin 'waist' of a true wasp. They have long antennæ. The fore wings of these sawflies have a lance-shaped cell with a straight cross-nervure. Larvae feed on a very wide variety of plants, each species is often restricted to one host; adults prey on flies and other insects in flowers.

Hypericum Perforatum
''Hypericum perforatum'', known as St. John's wort, is a flowering plant in the family Hypericaceae and the type species of the genus ''Hypericum''. Possibly a hybrid between '' H. maculatum'' and '' H. attenuatum'', the species can be found across temperate areas of Eurasia and has been introduced as an invasive weed to much of North and South America, as well as South Africa and Australia. While the species is harmful to livestock and can interfere with prescription drugs, it has been used in folk medicine over centuries, and remains commercially cultivated in the 21st century. Hyperforin, a phytochemical constituent of the species, is under basic research for possible therapeutic properties. Description ''Hypericum perforatum'' is an herbaceous perennial plant with extensive, creeping rhizomes. Its reddish stems are erect and branched in the upper section, and can grow up to high. The stems are woody near their base and may appear jointed from leaf scars. The branche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypericum
''Hypericum'' is a genus of flowering plants in the family Hypericaceae (formerly considered a subfamily of Clusiaceae). The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. Many ''Hypericum'' species are regarded as invasive species and noxious weeds. All members of the genus may be referred to as St. John's wort, and some are known as goatweed. The white or pink flowered marsh St. John's worts of North America and eastern Asia are generally accepted as belonging to the separate genus ''Triadenum'' Raf. ''Hypericum'' is unusual for a genus of its size because a worldwide taxonomic monograph was produced for it by Norman Robson (working at the Natural History Museum, London). Robson recognizes 36 sections within ''Hypericum''. Description ''Hypericum'' species are quite variable in habit, occurring as trees, shrubs, annuals, and perennials. Trees in the sense of single stemmed woody plants are rare, as most woody s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Ludwig Christian Gravenhorst
Johann Ludwig Christian Carl Gravenhorst (14 November 1777 – 14 January 1857), sometimes Jean Louis Charles or Carl, was a German entomologist, herpetologist, and zoologist. Life Gravenhorst was born in Braunschweig. His early interest in insects was encouraged by two of his professors, both amateur entomologists. He entered the University of Helmstedt to study law in 1797. However, the death of his father two years later left him a great fortune; so he was able to change his direction. He enrolled at the University of Göttingen where he followed the courses of Johann Friedrich Blumenbach. He returned to present his thesis to Helmstädt on a subject of entomology. He went to Paris in 1802 and there met Georges Cuvier, Pierre André Latreille, and Alexandre Brongniart. Parallel to his studies, he assembled, thanks to his financial means, a very important natural history collection. In 1805, he obtained a professorial chair in Göttingen and published the following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
