Palystes Castaneus
''Palystes castaneus'' is a species of huntsman spider found in parts of South Africa. It is common from Cape Town to Heidelberg, Western Cape, especially in forested areas. In scrub outside forested areas, it is replaced by ''Palystes superciliosus''. It occurs mainly on plants, where it hunts insects. It has a body length of 17–22 mm. ''P. castaneus'' is the type species for the genus ''Palystes'', and was first described by Pierre André Latreille in 1819. Spiders in the genus ''Palystes'' are commonly called rain spiders, or lizard-eating spiders. ''P. castaneus'' often appears in the home just before the onset of rain, where they hunt geckos (usually '' Afrogecko porphyreus''). Males are regularly seen from August to December, probably looking for females. After mating in the early summer, the female constructs a round egg sac about 60–100 mm in size made of silk, with twigs and leaves woven into it. These egg sacs are commonly seen from about November to Apri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palystes
''Palystes'' is a genus of huntsman spiders, commonly called rain spiders or lizard-eating spiders, occurring in Africa, India, Australia, and the Pacific. The most common and widespread species is '' P. superciliosus'', found in South Africa, home to 12 species in the genus. The name ''Palystes'' is derived from either the Latin ''palaestes'' or the Greek ''palaistes'', meaning "wrestler". The genus was first described by Ludwig Carl Christian Koch in 1875. Build ''Palystes'' species are large spiders, with a body length of 15–36 mm, and a leg span up to 110 mm. Their top side is covered in tan to dark tan velvety setae (hairs). The underside of their legs is banded in colour, and their legs and abdomens may be interspersed with slightly longer setae. They have a large moustachial stripe below their front eyes, and extending down their fangs. Habits While ''Palystes'' species mostly hunt insects on plants, they commonly enter houses before rain, or during the summer ...

Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Sparassidae
Huntsman spiders, members of the family Sparassidae (formerly Heteropodidae), are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places (forests, mine shafts, woodpiles, wooden shacks). In southern Africa the genus ''Palystes'' are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related. More than a thousand Sparassidae species occur in most warm temperate to tropical regions of the world, including much of Australasia, Africa, Asia, the Mediterranean Basin, and the Americas. Several species of huntsman spider can use an unusual form of locomotion. The wheel spider (''Carparachne aureoflava'') from the Namib uses a cartwheeling motion which gives it its name, while ''Cebrennus rechenbergi ...

Endemic Fauna Of South Africa
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tachypompilus Ignitus
The rain spider wasp or red-femora spider wasp (''Tachypompilus ignitus'') is an Afrotropical species of spider wasp specialising in capturing spiders of the genus ''Palystes'', the rain spiders. Distribution This spider wasp is found in Southern Africa, recorded from South Africa and Zimbabwe. Description These wasps are about 45 mm in length. They are largely black with orange antennae, orange dital parts of the legs, and largely orange wings, which are dark at the base and tip. Biology Females of ''T. ignites'' largely specialise in hunting and capturing rain spiders ''Palystes'' spp., which are stung by the wasp; the sting paralyses the spider which is dragged to the wasp's nest. In the nest, the wasp lays an egg on the spider and then seals the nest. When the larva A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults.

Pupate
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphos ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Spider Wasp
Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps. The family is cosmopolitan, with some 5,000 species in six subfamilies. Nearly all species are solitary (with the exception of some group-nesting Ageniellini), and most capture and paralyze prey, though members of the subfamily Ceropalinae are kleptoparasites of other pompilids, or ectoparasitoids of living spiders. In South America, species may be referred to colloquially as or , though these names can be generally applied to any very large stinging wasps. Furthermore, in some parts of Venezuela and Colombia, it is called , or "horse killers", while in Brazil some particular bigger and brighter species of the general kind might be called /, or "throat locker". Morphology Like other strong fliers, pompilids have a thorax modified for efficient flight. The metathorax is solidly fused to the pronotum and mesothorax; moreover, the prothorax is best developed in Pompilidae a ...

Paralysed
Paralysis (also known as plegia) is a loss of motor function in one or more muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed with some form of permanent or transient paralysis. The word "paralysis" derives from the Greek παράλυσις, meaning "disabling of the nerves" from παρά (''para'') meaning "beside, by" and λύσις (''lysis'') meaning "making loose". A paralysis accompanied by involuntary tremors is usually called "palsy". Causes Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson's disease, ALS, botulism, spina bifida, multiple sclerosis, and Guillain–Barré syndrome. Temporary paralysis occurs during REM sleep, and dysregulation of this system can le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
