Araneus Gemma
''Araneus'' is a genus of common orb-weaving spiders. It includes about 650 species, among which are the European garden spider and the barn spider. The genus was erected by Carl Alexander Clerck in 1757. Description Spiders of this genus present perhaps the most obvious case of sexual dimorphism among all of the orb-weaver family, with males being normally to the size of females. In ''A. diadematus'', for example, last-molt females can reach the body size up to 1 in (2.5 cm), while most males seldom grow over 0.3 in (1 cm), both excluding leg span. Males are differentiated from females by a much smaller and more elongated abdomen, longer legs, and the inability to catch or consume prey bigger than themselves. In females, the epigyne has a long scape (a tongue-like appendage). Male pedipalps have a hook-like terminal apophysis. Abdominal tubercles are present anterolaterally. Taxonomic history ''Araneus'' was, for much of its history, called ''Epeira''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araneus Diadematus
The spider species ''Araneus diadematus'' is commonly called the European garden spider, cross orbweaver, diadem spider, orangie, cross spider, and crowned orb weaver. It is sometimes called the pumpkin spider, although this name is also used for a different species, '' Araneus marmoreus''. It is an orb-weaver spider found in Europe, where it is native, and North America, where it was introduced. Range ''A. diadematus'' has a holarctic distribution throughout Europe and across North America, from southern Canada to Mexico, and from British Columbia to Newfoundland.Cross Spider Washington NatureMapping Project Size and markings [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junior Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, ...

Uloboridae
Uloboridae is a family of non- venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body. Description They are medium to large spiders, with three claws, which lack venomous glands. They build a spiral web using cribellate silk, which is quite fuzzy. They are usually dull in color, and are able to camouflage well into their surroundings. They typically have a humped opisthosoma, which is notoriously more humped than the carapace. Their rear eyes tend to curve, more so in some species than others. Most uloborid spiders have eight eyes, but the genus '' Miagrammopes'' has only four. Hunting The hunting method of these spiders is quite unique among all animals in the kingdom. These spiders do not use an adhesive on their orb webs, but rather the very fine cribellate fibers on ...

Titanoecidae
Titanoecidae is a family of araneomorph spiders first described by Pekka T. Lehtinen in 1967. It is fairly widespread in the New World and Eurasia with five genera and more than 50 species worldwide. These are mostly dark-colored builders of "woolly" ( cribellate) silk webs. Several species are found at relatively high altitudes in mountain ranges and may be very common in such habitats.

Ludwig Carl Christian Koch
Ludwig Carl Christian Koch (8 November 1825 – 1 November 1908) was a German entomologist and arachnologist. He was born in Regensburg, Germany, and died in Nuremberg, Germany. He studied in Nuremberg, initially law, but then turned to medicine and science. From 1850, he practiced as a physician in the Wöhrd district of Nuremberg. He is considered among the four most influential scientists on insects and spiders in the second half of the 19th century. He wrote numerous works on the arachinoids of Europe, Siberia, and Australia. His work earned him worldwide reputation as "Spider Koch". Sometimes confused with his father Carl Ludwig Koch (1778–1857), another famous arachnologist, his name is abbreviated L.Koch on species descriptions; his father's name is abbreviated C.L.Koch Pierre Bonnet.

Theridiosoma Gemmosum
''Theridiosoma gemmosum'' is a species of spider in the family Theridiosomatidae, known as ray spiders. It is widely distributed in the Holarctic region. A small spider with a shiny globular abdomen, it constructs a conical orb web. Description ''Theridiosoma gemmosum'' is a small spider. Females are 2–3 mm long, males smaller still at 1.5–2 mm. In both sexes, the carapace (upper surface of the cephalothorax) is dark brown; the upper surface of the abdomen (opisthosoma) is silvery with variable dark lines and marks. The abdomen is globular, more or less circular from above. The male palpal bulbs and the female epigyne are distinctive. Web ''Theridiosoma gemmosum'' constructs a small orb web. The radii do not run directly to a central hub as with other orb webs, but are first joined into groups of two or three before combining to meet in the middle. A single thread runs from the centre to a nearby support, and is held by the spider. While the spider is holding this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theridiosomatidae
Theridiosomatidae, commonly known as ray spiders, are a family of araneomorph spiders first described by Eugène Simon in 1881. The family includes 137 species divided between 20 genera. They are most recognizable for their construction of cone-shaped webs. The cephalothorax of Theridiosomatidae includes one pair of labio-sternal glands which seems a characteristic of the family and could be considered as a variation of segmental glands opening on the base of prosomatic appendages in various Spiders. This organ is composed of a cuticular sack-like reservoir opening on the sternum via a "pit", and of a cluster of functional units belonging to the class 3 of arthropodian epidermal glands. Each unit includes a large adenocyte provided with characteristic foliaceous microvilli (heart-shaped in Naatlo) and numerous mitochondria, an excretory duct terminating to a pore (located on an "apophysis" in Wendilgarda) and canal cells. Present in immature and both sexes, the labiosternal gland e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theridiidae
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of Araneomorphae, araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genus, genera, and is the most common arthropod found in human dwellings throughout the world. Theridiid spiders are both Entelegynae, entelegyne, meaning that the females have a genital plate, and Cribellum, ecribellate, meaning that they spin sticky capture silk instead of woolly silk. They have a comb of serrated bristles (setae) on the Arthropod leg, tarsus of the fourth leg. The family includes some model organisms for research, including the List of medically significant spider bites, medically important Latrodectus, widow spiders. They are important to studies characterizing their venom and its clinical manifestation, but widow spiders are also used in research on spider silk and sexual biology, including ...

Tetragnathidae
Long-jawed orb weavers or long jawed spiders (Tetragnathidae) are a family of araneomorph spiders first described by Anton Menge in 1866. They have elongated bodies, legs, and chelicerae, and build small orb webs with an open hub with few, wide-set radii and spirals with no signal line or retreat. Some species are often found in long vegetation near water.
