Hedychrum Rutilans
''Hedychrum rutilans'' is a species of cuckoo wasps (insects in the family Chrysididae). The species occurs primarily in Austria, Italy, Bulgaria, Greece, France, Poland, Portugal, Spain, Switzerland and in North Africa.Agnoli, G. L.; Rosa, P. (2011)Hedychrum rutilans Dahlbom, 1854 - Database of the Italian Chrysididae on Chrysis.net/ref> The head and thorax are metallic green with red spots, while the abdomen is red. The color is more green and partially golden in the male and more extensively golden-red in the female. The body is somewhat hairy. Biology ''Hedychrum rutilans'' is a cleptoparasite and parasitoid of larvae of beewolves ('' Philanthus triangulum'' and ''Philanthus coronatus''). The female cuckoo wasp lays its eggs on the paralyzed honeybee workers serving as provisions for the beewolf larvae, placed by the female beewolf in its brood cells. The cuckoo wasp larvae feed on the honeybees and on the larvae of the beewolf. Adults grow up to long and can be encoun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anders Gustaf Dahlbom
Anders Gustaf Dahlbom (3 March 1806 – 3 May 1859) was a Swedish entomologist. Dahlbom was born in Härberga parish in Östergötland County, son of a military surgeon. He matriculated at Lund University in 1825, completed his filosofie magister degree in 1829, became a docent of natural history in 1830, acting adjunct of entomology in 1841, adjunct in 1843 and keeper of the Entomological collections and professor extraordinary in 1857. Supported by public funds, he made several research journeys, especially to northern Sweden and the mountain regions, where he first accompanied his teacher, the dipterologist Johan Wilhelm Zetterstedt Johan Wilhelm Zetterstedt (20 May 1785 – 23 December 1874) was a Swedish naturalist who worked mainly on Diptera and Hymenoptera. Biography Zetterstedt studied at the University of Lund, where he was a pupil of Anders Jahan Retzius. He rec ..., as well as to other parts of the country and abroad, and published his observations in vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of Europe
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysididae
Commonly known as cuckoo wasps or emerald wasps, the hymenopteran family Chrysididae is a very large cosmopolitan group (over 3000 described species) of parasitoid or kleptoparasitic wasps, often highly sculptured, with brilliant metallic colors created by structural coloration. They are most diverse in desert regions of the world, as they are typically associated with solitary bee and wasp species, which are also most diverse in such areas. Their brood parasitic lifestyle has led to the evolution of fascinating adaptations, including chemical mimicry of host odors by some species. Nomenclature The term "cuckoo wasp" refers to the cuckoo-like way in which wasps in the family lay eggs in the nests of unrelated host species. The term is also used for some wasps outside of the family, such as '' Sapyga louisi''. Chrysididae, the scientific name of the family, refers to their shiny bodies and is derived from Greek ''chrysis, chrysid-'', "gold vessel, gold-embroidered dress", plus ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand, for example, aragonite, which has mostly been created, over the past 500million years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean. Somewhat more rarely, sand may be composed of calciu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphorbia Paralias
''Euphorbia paralias'', the sea spurge, is a species of flowering plant in the family Euphorbiaceae, native to Europe, northern Africa and western Asia. The species is widely naturalised in Australia. It invades coastal areas, displacing local species and colonising open sand areas favoured by certain nesting birds. Major eradication programmes have been undertaken in some areas, for example by Sea Spurge Remote Area Teams in Tasmania, with great success. Description It is an erect, glaucous, perennial plant growing up to 70 cm tall. The plant has many stems, dividing into 3-5 fertile branches, each branching further. The cauline leaves (arising from the stem, without stalk) are crowded, overlapping, elliptic-ovate (ovate toward the top of the stems), fleshy and 5 to 20 mm long. Leaves on fertile branches are circular-rhombic or reniform. Flower head on a solitary cyathia A cyathium (plural: cyathia) is one of the specialised pseudanthia ("false flowers") formin ...

Achillea Millefolium
''Achillea millefolium'', commonly known as yarrow () or common yarrow, is a flowering plant in the family Asteraceae. Other common names include old man's pepper, devil's nettle, sanguinary, milfoil, soldier's woundwort, and thousand seal. The plant is native to temperate regions of the Northern Hemisphere in Asia, Europe, and North America. It has been introduced as a feed for livestock in New Zealand and Australia. Description ''Achillea millefolium'' is an erect, herbaceous, perennial plant that produces one to several stems in height, and has a spreading rhizomatous growth form. Leaves are evenly distributed along the stem, with the leaves near the middle and bottom of the stem being the largest. The leaves have varying degrees of hairiness (pubescence). The leaves are long, bipinnate or tripinnate, almost feathery, and arranged spirally on the stems. The leaves are cauline, and more or less clasping, being more petiolate near the base. The inflorescence has 4 to 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mentha
''Mentha'' (also known as mint, from Greek , Linear B ''mi-ta'') is a genus of plants in the family Lamiaceae (mint family). The exact distinction between species is unclear; it is estimated that 13 to 24 species exist. Hybridization occurs naturally where some species' ranges overlap. Many hybrids and cultivars are known. The genus has a subcosmopolitan distribution across Europe, Africa - (Southern Africa), Asia, Australia - Oceania, North America and South America. Its species can be found in many environments, but most grow best in wet environments and moist soils. Description Mints are aromatic, almost exclusively perennial herbs. They have wide-spreading underground and overground stolons and erect, square, branched stems. Mints will grow 10–120 cm (4–48 inches) tall and can spread over an indeterminate area. Due to their tendency to spread unchecked, some mints are considered invasive. The leaves are arranged in opposite pairs, from oblong to lanceol ...

Honeybee
A honey bee (also spelled honeybee) is a eusocial flying insect within the genus ''Apis'' of the bee clade, all native to Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America (early 16th century), North America (early 17th century), and Australia (early 19th century). Honey bees are known for their construction of perennial colonial nests from wax, the large size of their colonies, and surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. Only eight surviving species of honey bee are recognized, with a total of 43 subspecies, though historically 7 to 11 species are recognized. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. The best known honey bee is the western honey ...

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...
