Rhadinoceraea Micans
The iris sawfly (''Rhadinoceraea micans'') is a species of sawfly in the family '' Tenthredinidae''. Native to Europe, the larvae — more often noticed than the adults — can occur in large numbers causing damage to garden plants such as the yellow iris or flag, '' Iris pseudacorus''. Description Adult The adult sawfly is shiny, black, and hairy. The antennae are thick, and longer than head and thorax combined. The wings are slightly smoky. The head is as wide as the thorax. Larva The larvae, up to 1 inch (25 mm) long, look like caterpillars but have six pairs of prolegs rather than five. The head is shiny black; the body greenish brown, becoming darker with age. There are double rows of white dots around the segments. Larval host plants are all waterside irises, including '' Iris pseudacorus'', '' Iris ensata'', ''Iris laevigata'', ''Iris spuria'' and ''Iris versicolor ''Iris versicolor'' is also commonly known as the blue flag, harlequin blueflag, larger ...

Johann Christoph Friedrich Klug
Johann Christoph Friedrich Klug (5 May 1775, in Berlin – 3 February 1856, in Berlin), was a German entomologist. He described the butterflies and some other insects of Upper Egypt and Arabia in Christian Gottfried Ehrenberg and Wilhelm Friedrich Hemprich's ''Symbolæ Physicæ'' (Berlin, 1829–1845). He was professor of medicine and entomology in the University of Berlin (known in the present day as the Humboldt University of Berlin) where he curated the insect collections from 1810 to 1856. At the same time he directed the Botanic Garden in Berlin which contains his collections. Klug worked mainly on Hymenoptera and Coleoptera. The plant genus '' Klugia'' (now called '' Rhynchoglossum'', Family Gesneriaceae) was named in his honour as well as the butterflies ''Geitoneura klugii'' and '' Heliophisma klugii''. In 1855, he was elected a foreign member of the Royal Swedish Academy of Sciences. Works (Partial List) * Die Blattwespen nach ihren Gattungen und Arten zusammengestellt. ...

Tenthredo
''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.

Sawfly
Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies. The primary distinction between sawflies and the Apocrita – the ants, bees, and wasps – is that the adults lack a "wasp waist", and instead have a broad connection between the abdomen and the thorax. Some sawflies are Batesian mimics of wasps and bees, and the ovipositor can be mistaken for a stinger. Sawflies vary in len ...

Tenthredinidae
Tenthredinidae is the largest family of sawflies, with well over 7,500 species worldwide, divided into 430 genera. Larvae are herbivores and typically feed on the foliage of trees and shrubs, with occasional exceptions that are leaf miners, stem borers, or gall makers. The larvae of externally feeding species resemble small caterpillars. As with all hymenopterans, common sawflies undergo complete metamorphosis. The family has no easily seen diagnostic features, though the combination of five to nine antennal flagellomeres plus a clear separation of the first abdominal tergum from the metapleuron can reliably separate them. These sawflies are often black or brown, and 3 to 20 mm long. Like other sawflies, they lack the slender "wasp-waist", or petiole, between the thorax and abdomen, characteristic of many hymenopterans. The mesosoma and the metasoma are instead broadly joined. The Tenthredinidae are also often somewhat dorsoventrally flattened, which will distinguish them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pest (organism)
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Ma ...s, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwor ...

Iris Pseudacorus
''Iris pseudacorus'', the yellow flag, yellow iris, or water flag, is a species of flowering plant in the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet ''pseudacorus'' means "false acorus", referring to the similarity of its leaves to those of ''Acorus calamus'' (sweet flag), as they have a prominently veined mid-rib and sword-like shape. However, the two plants are not closely related. The flower is commonly attributed with the fleur-de-lis. Description This herbaceous flowering perennial plant grows to , or a rare tall, with erect leaves up to long and broad. The flowers are bright yellow, across, with the typical iris form. The fruit is a dry capsule long, containing numerous pale brown seeds. ''I. pseudacorus'' grows best in very wet conditions, and is common in wetlands, where it tolerates submersion, low pH, and anoxic soils. The plant spreads quickly, by both rhizome and water-dispersed seed. It fills a simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow Flag Iris Sawfly (Rhadinoceraea Micans) Showing Damage To Plant
Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths (green, blue, and violet). Because it was widely available, yellow ochre pigment was one of the first colors used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old. Ochre and orpiment pigments were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proleg
A proleg is a small, fleshy, stub structure found on the ventral surface of the abdomen of most larval forms of insects of the order Lepidoptera, though they can also be found on other larval insects such as sawflies and a few other types of insects. In all the orders in which they appear, mainly Hymenoptera and Lepidoptera, prolegs of any form evolved independently of each other by convergent evolution. Prolegs of lepidopteran larvae have a small circle of gripping hooks, called "crochets". The arrangement of the crochets can be helpful in identification to family level. Although the point has been debated, prolegs are not widely regarded as true legs, derived from the primitive uniramous limbs. Certainly in their morphology they are not jointed, and so lack the five segments (coxa, trochanter, femur, tibia, tarsus) of thoracic insect legs. Prolegs do have limited musculature, but much of their movement is hydraulically powered. See also * Terrestrial locomotion in animals ...

Iris Ensata
''Iris ensata'', the Japanese iris or Japanese water iris (Japanese: ''hanashōbu''), formerly ''I. kaempferi'', is a species of flowering plant in the family Iridaceae, native to Japan, China, Korea and Russia, and widely cultivated as an ornamental plant. "Japanese iris" may also refer to '' I. sanguinea'' and '' I. laevigata'', both native to Japan. Description ''Iris ensata'' is an erect rhizomatous herbaceous perennial growing to tall, with strap-shaped leaves. The flower, appearing in midsummer, is purple with a flash of yellow on the falls. The bluish purple color of the flowers is an example of the copigmentation phenomenon. Habitat Widely distributed throughout the Japanese archipelago and elsewhere, ''I. ensata'' is very hardy down to . It prefers a boggy or marshy environment and soil with a low (acidic) pH. In favourable conditions it will eventually form sizable clumps. Cultivation ''Iris ensata'' is extensively grown as an ornamental plant in gardens and parks t ...

Iris Laevigata
''Iris laevigata'', known as Japanese iris, rabbit-ear iris, or shallow-flowered iris (Japanese: カキツバタ), is a species of flowering plant in the family Iridaceae, native to Japan. It is related to other members of ''Iris'' subgenus '' Limniris'', including other species of Japanese irises. It is found growing in shallow waters and seems to prefer marshy and still ponds, although it can also be grown in damp soil if conditions are right. Flowers are usually blue, purple or violet and have unique colour patterns including some types with predominantly white flowers with blue spots (''washino-o''), and dark purples bordered with white (''maikujaku''). Synonyms include ''I. albopurpurea'' and ''I. phragmitetorum''. Cultivation ''Iris laevigata'' differs from other Japanese irises mainly in being more dependent on water and in lacking the strong midrib of the foliage. When grown from seeds, it usually germinates in 30–545 days although even under good conditions germina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
