Phonognatha Graeffei
''Phonognatha graeffei'', referred to as the leaf curling spider, is a common Australian spider found in woodlands and urban areas in the northeastern, eastern and southern states. A small member of the family Araneidae, the orb-weavers, it was previously placed in 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-se .... The spider is distinguished by having a curled leaf at the centre of its web, in which it shelters. The species form pairs living together in the same leaf, though at opposite ends of their shelter, even before mating at maturity. The female creates a separate curled leaf "nursery" hung in foliage nearby. Appearance The body length of the male is 5 to 6mm and female 8 to 12mm. Males and females look very similar with red-brown legs and body and a cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Araneidae
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. With 3,108 species in 186 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families. The long-jawed orb weavers (Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Araneo ...

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. Systematics , the World Spider Catalog accepts the following extant genera: *''Alcimosphenus'' Simon, 1895 — Caribbean *'' Allende'' Álvarez-Padilla, 2007 — Chile, Argentina *'' Antillognatha'' Bryant, 1945 — Hispaniola *'' Atelidea'' Simon, 1895 — Sri Lanka *'' Azilia'' Keyserling, 1881 — United States, Panama, South America, Caribbean *''Chrysometa'' Simon, 1894 — South America, Central America, Mexico, Caribbean *''Cyrtognatha'' Keyserling, 1881 — South America, Central America, Caribbean, Mexico *'' Dianleucauge'' Song & Zhu, 1994 — China *'' Diphya'' Nicolet, 1849 — Asia, South America, Africa *''Dolic ...

Phonognatha Eye Group
''Phonognatha'' is a genus of South Pacific orb-weaver spiders first described by Eugène Simon in 1895. It was originally placed with the long-jawed orb weavers, and was moved to ''Araneidae'' in 2008. The leaf curling spider (''Phonognatha graeffei'') is a common Australian spider found in urban areas as well as woodlands of the northeastern, eastern, and southern states. ''Phonognatha vicitra'' was formerly placed in the genus, but it has been shown to be a misidentification of ''Acusilas coccineus''. Species it contains four species: *''Phonognatha graeffei'' (Keyserling, 1865) (type) – Australia *''Phonognatha melania'' ( L. Koch, 1871) – Australia *''Phonognatha neocaledonica'' Berland, 1924 – New Caledonia *''Phonognatha tanyodon ''Phonognatha'' is a genus of South Pacific orb-weaver spiders first described by Eugène Simon in 1895.

Leaf Curling Spider In Retreat With Web 1
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of '' Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper ( adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs l ...

Two Retreats In Urban Garden 1
2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and only even prime number. Because it forms the basis of a duality, it has religious and spiritual significance in many cultures. Evolution Arabic digit The digit used in the modern Western world to represent the number 2 traces its roots back to the Indic Brahmic script, where "2" was written as two horizontal lines. The modern Chinese and Japanese languages (and Korean Hanja) still use this method. The Gupta script rotated the two lines 45 degrees, making them diagonal. The top line was sometimes also shortened and had its bottom end curve towards the center of the bottom line. In the Nagari script, the top line was written more like a curve connecting to the bottom line. In the Arabic Ghubar writing, the bottom line was completely vertical, and the digit looked like a dotless closing question mark. Restoring the bottom line to its original hori ...

Spiders Of Australia
Australia has a number of highly venomous spiders, including the Sydney funnel-web spider, its relatives in the family Hexathelidae, and the redback spider, whose bites can be extremely painful and have historically been linked with deaths in medical records. Most Australian spiders do not have venom that is considered to be dangerously toxic. No deaths caused by spider bites in Australia have been substantiated by a coronial inquest since 1979. There are sensationalised news reports regarding Australian spiders that fail to cite evidence. ''A Field Guide to Spiders of Australia'' published by CSIRO Publishing in 2017 featuring around 836 species illustrated with photographs of live animals, around 381 genera and 78 families, introduced significant updates to taxonomy from Ramirez, Wheeler and Dmitrov Estimates put the total number of Australian spider species at about 10,000. Only around 3,600 have been described. Little information is known about many undiscovered species. New s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
