Andrena Hattorfiana
''Andrena hattorfiana'' is a species of ''mining bees'' belonging to the family Andrenidae subfamily Andreninae. Description The adults grow up to long. They have a black-brown body with sparse light hair, while the first and the second abdominal segment are reddish. The females have a pollen basket of curved hairs on the sides of the thorax.

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Insects Described In 1775
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Inse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andrena
''Andrena'' is a genus of bees in the family Andrenidae. With over 1,500 species, it is one of the largest genera of animals. It is a strongly monophyletic group that is difficult to split into more manageable divisions; currently, ''Andrena'' is organized into 104 subgenera. It is nearly worldwide in distribution, with the notable exceptions of Oceania and South America. Bees in this genus are commonly known as mining bees due to their ground-nesting lifestyle. Morphology ''Andrena'' are generally medium-sized bees; body length ranges between 8 and 17 mm with males being smaller and more slender than females. Most are black with white to tan hair, and their wings have either two or three submarginal cells. They carry pollen mainly on femoral scopal hairs, but many ''Andrena'' have an additional propodeal corbicula for carrying some pollen on their thorax. C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, Johns Hopkins University Press. They can be distin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Von Hattorf
The term ''von'' () is used in German language surnames either as a nobiliary particle indicating a noble patrilineality, or as a simple preposition used by commoners that means ''of'' or ''from''. Nobility directories like the ''Almanach de Gotha'' often abbreviate the noble term ''von'' to ''v.'' In medieval or early modern names, the ''von'' particle was at times added to commoners' names; thus, ''Hans von Duisburg'' meant "Hans from he city ofDuisburg". This meaning is preserved in Swiss toponymic surnames and in the Dutch or Afrikaans ''van'', which is a cognate of ''von'' but does not indicate nobility. Usage Germany and Austria The abolition of the monarchies in Germany and Austria in 1919 meant that neither state has a privileged nobility, and both have exclusively republican governments. In Germany, this means that legally ''von'' simply became an ordinary part of the surnames of the people who used it. There are no longer any legal privileges or constraints assoc ...

Stylops Melittae
''Stylops melittae'' is a species of the order Strepsiptera of flying insects, that parasitize various species of sand bees (''Andrena'').Bleidorn, Christoph; Feitz, Fernand; Schneider, Nico; Venne, Christian''Zum Vorkommen von Stylops melittae Kirby, 1802 (Insecta, Strepsiptera) in Luxemburg''Bull. Soc. Nat. luxemb. 105 (2004) p. 137–142 Biology The female ''Stylops melittae'' gives birth to a large number of motile primary larvae, that are strewn upon blossoms. From there they can be delivered along with the pollen at the nest construction of the sand bees for which the species is specialized. In the nest construction the primary larvae penetrate into the host larvae and molt into exclusively endoparasitic secondary larvae. These roam about feeding in the host, and after a few further moltings establish themselves in the abdomen, and with their anterior portion break through between two abdominal segments of the host's skin, where they pupate. The exit point lays mostly betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomada Armata
With over 850 species, the genus ''Nomada'' is one of the largest genera in the family Apidae, and the largest genus of kleptoparasitic "cuckoo bees." Kleptoparasitic bees are so named because they enter the nests of a host and lay eggs there, stealing resources that the host has already collected. The name "''Nomada''" is derived from the Greek word ''nomas ( νομάς''), meaning "roaming" or "wandering." ''Nomada'' parasitize many different types of bees as hosts, primarily the genus ''Andrena,'' but also ''Agapostemon, Melitta, Eucera'' and ''Exomalopsis''. As parasites, they lack a pollen-carrying scopa, and are mostly hairless, as they do not collect pollen to feed their offspring. Like non-parasitic bees, adults are known to visit flowers and feed on nectar. Given the lack of scopa and general behavior, they are considered poor pollinators. Appearance and identification They are often extraordinarily wasp-like in appearance, with red, black, and yellow colors prevaili ...

Cuckoo Bee
The term cuckoo bee is used for a variety of different bee lineages which have evolved the kleptoparasitism, kleptoparasitic behaviour of laying their eggs in the nests of other bees, reminiscent of the behavior of cuckoo birds. The name is perhaps best applied to the apidae, apid subfamily Nomadinae, but is commonly used in Europe to mean bumblebees ''List of bumblebee species, Bombus'' subgenus ''Psithyrus''. Females of cuckoo bees are easy to recognize in almost all cases, as they lack pollen collecting structures (the scopa (biology), scopa) and do not construct their own nests. They often have reduced body hair, abnormally thick and/or heavily sculptured exoskeleton, and saber-like mandible (insect), mandibles, although this is not universally true; other less visible changes are also common. They typically enter the nests of pollen-collecting species, and lay their eggs in cells provisioned by the host bee. When the cuckoo bee larva hatches it consumes the host larva's pollen ...

Knautia Arvensis
''Knautia arvensis'', commonly known as field scabious, is a herbaceous perennial species of flowering plant in the honeysuckle family Caprifoliaceae. Description It is a perennial plant that grows between . It prefers grassy places and dry soils, avoiding heavy soils, and flowers between July and September. The flowers are borne on inflorescences in the form of heads; each head contains many small florets. The head is flatter than in similar species, such as devil's bit scabious (''Succisa pratensis'') and small scabious (''Scabiosa columbaria''). There are 4 stamens in each floret, and 1 notched long stigma. The fruit is nut like, cylindrical and hairy, in size. It has a tap root. The stem has long stiff hairs angled downwards. The leaves form a basal rosette, are paired on the stem, the lowest typically long, spear shaped, whereas the upper are smaller. There are no stipules.
