Anthicidae Anthelephila Cyanea
The Anthicidae are a family of beetles that resemble ants. They are sometimes called ant-like flower beetles or ant-like beetles. The family comprises over 3,500 species in about 100 genera. Description Their heads constrict just in front of the pronotum, forming a neck, and the posterior end of the pronotum is usually narrow as well. Legs and antennae are slender, heightening the ant-like appearance, and the body is sparsely covered with setae. Biology Adult beetles are omnivorous, being known to consume small arthropods, pollen, fungi, and whatever else they can find. Some species are of interest as biological control agents, as they can eat the eggs or larvae of pests. Larvae are either omnivorous, predators, or fungus-eaters; the young of one species of ''Notoxus'' have been observed boring into sweet potato tubers. Many members of the family are attracted to cantharidin, which they seem to accumulate and that deters possible predators. Taxonomy Synonyms of the family in ...

Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis''. He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive, then in the province of Limousin, as the illegitimate child of Jean Joseph Sahuguet d'Amarzit, général ...

Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Beetles
''American Beetles'' is the single most comprehensive description of the beetles of North America north of the tropical area of Mexico. It was started by Ross H. Arnett, Jr. as an update of his classic ''The Beetles of the United States''; along with Michael C. Thomas, he enlisted more than 60 specialists to write treatments of each family. The work outlived Arnett, and was published by CRC Press in 2001 (vol. 1) and 2002 (vol. 2). This is a highly technical book, with extensive references to the literature. The introduction includes a section on beetle anatomy that introduces all the technical terms used later. The bulk of the content consists of treatments of the 130-odd families known to occur in North America (a couple dozen are not known from North America, and are not described); the descriptive material applies worldwide, and there are brief notes about non-North American family members. A family treatment consists of a morphological description, including the larvae if ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Donald S
Donald is a masculine given name derived from the Gaelic name ''Dòmhnall''.. This comes from the Proto-Celtic *''Dumno-ualos'' ("world-ruler" or "world-wielder"). The final -''d'' in ''Donald'' is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers, and partly associated with the spelling of similar-sounding Germanic names, such as ''Ronald''. A short form of ''Donald'' is ''Don''. Pet forms of ''Donald'' include ''Donnie'' and ''Donny''. The feminine given name ''Donella'' is derived from ''Donald''. ''Donald'' has cognates in other Celtic languages: Modern Irish ''Dónal'' (anglicised as ''Donal'' and ''Donall'');. Scottish Gaelic ''Dòmhnall'', ''Domhnull'' and ''Dòmhnull''; Welsh '' Dyfnwal'' and Cumbric ''Dumnagual''. Although the feminine given name ''Donna'' is sometimes used as a feminine form of ''Donald'', the names are not etymologically related.

Lebanese Amber
Lebanese amber is fossilized resin found in Lebanon and southwest Syria. It dates back approximately 130-125 million years to the Barremian of the Early Cretaceous. It formed on what was then the northern coast of Gondwana, believed to be a tropical or subtropical zone in a temperate or hot climate. It is the oldest source of amber with a significant number of inclusions. Up to 300 sources of Lebanese amber have been recovered and 17 of them are important sources of organic inclusions, which are the oldest of their kind. The inclusions help to document Cretaceous fauna and flora. Origins Lebanese amber can be found in Lebanon and neighboring areas of Syria and north Palestine. Up to 300 different sources of amber had been discovered by 2010. The amber was deposited in the Cretaceous era and is rich in fossil synclusions. 19 of the discovered sources are rich in inclusions from the Early Cretaceous. All of them are located in Lebanon, which makes it the largest source of inclusion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma (million years ago) and 121.4 ± 1.0 Ma). It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and followed by the Aptian Stage.See Gradstein ''et al.'' (2004) or the online geowhen database (link below) Stratigraphic definitions The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France. Henri Coquand defined the stage and named it in 1873. The base of the Barremian is determined by the first appearance of the ammonites ''Spitidiscus hugii'' and ''Spitidiscus vandeckii''. The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite '' Paradeshayesites oglanlensis''. Regional equivalents The Barremian falls in the Gallic epoch, a su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Cantharidin
Cantharidin is an odorless, colorless fatty substance of the terpenoid class, which is secreted by many species of blister beetles. It is a burn agent or a poison in large doses, but preparations containing it were historically used as aphrodisiacs (Spanish fly). In its natural form, cantharidin is secreted by the male blister beetle and given to the female as a copulatory gift during mating. Afterwards, the female beetle covers her eggs with it as a defense against predators. Poisoning from cantharidin is a significant veterinary concern, especially in horses, but it can also be poisonous to humans if taken internally (where the source is usually experimental self-exposure). Externally, cantharidin is a potent vesicant (blistering agent), exposure to which can cause severe chemical burns. Properly dosed and applied, the same properties have also been used therapeutically, for instance for treatment of skin conditions such as molluscum contagiosum infection of the skin. Cantharidi ...

Sweet Potato
The sweet potato or sweetpotato (''Ipomoea batatas'') is a dicotyledonous plant that belongs to the Convolvulus, bindweed or morning glory family (biology), family, Convolvulaceae. Its large, starchy, sweet-tasting tuberous roots are used as a root vegetable. The young shoots and leaves are sometimes eaten as Leaf vegetable, greens. Sweet potato cultivars, Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Sweet potato is only distantly related to the common potato (''Solanum tuberosum''), both being in the order Solanales. Although darker sweet potatoes are often referred to as "yams" in parts of North America, the species is not a yam (vegetable), true yam, which are monocots in the order Dioscoreales. Sweet potato is native to the tropical regions of the Americas. Of the approximately 50 Convolvulaceae#Genera, genera and more than 1,000 species of Convolvulaceae, ''I. batatas'' is the only crop plant of major importance—some o ...
