Pycna sylvia(Distant, 1899)

Platypleura sylvia is a species of cicada endemic to South Africa. It was first described and named by William Lucas Distant in 1899 in the Annals and Magazine of Natural History . [1] Insecta transvaaliensia was self-published by Distant and appeared in twelve parts over the period 1900-1911. The series was an account of Distant's insect-collecting trips through the Transvaal. The collected parts were published as a single volume after Distant's death by Francis Edwards of London in 1924.

Specimens of this species were collected in 1906 and then not found again in the field until 2001 "when small, localised populations were discovered during a faunal survey for the Environmental Management Programme Report for the Anglo Platinum Der Brochen Platinum project in the Groot Dwars River valley, Mpumalanga." - Platypleura sylvia As a result a behavioural study was carried out in the Groot Dwars River valley in 2001 and 2002, during which researchers found that the adult life stage of the insect lasted six to eight weeks during the months of November and December, and that its distribution is extremely localised and confined to a number of valleys in Sekhukhuneland. This cicada is found in closed bushveld that includes the tree Vitex obovata , a member of the Verbenaceae, a tree also endemic to South Africa and Swaziland, and with which it has a close and exclusive relationship. A number of cicadas have evolved this affinity for a single species of tree. Researchers observed a female drilling holes in a dry twig and depositing her eggs. Males spread their wings and arch their backs when calling, a posture which is believed to amplify their call, best described as "zeep".

Cicada nymphs were found down to 50 centimetres (20 in) below the soil surface attached to the roots of Vitex obovata and exuviae were found above ground on trees of the same species housing calling adults, and on other plant species when no adults were present. The duration of the larval stage is as yet undetermined, but is thought to be something of the order of six or seven years underground.

P. sylvia is confined to the valley of the Groot Dwars River (24°55′ S, 30°05′ E), a tributary of the Steelpoort River, and occurs on the farms Helena, Der Brochen, Mareesburg and also the Didingwe River Lodge property, with a slight spill-over to neighbouring areas. The species' tragedy is its occurrence on geological formations rich in platinum. The area is actively mined by the Anglo American Platinum Corporation committed to "minimising its environmental impact at this operation by implementing best practice in land and environmental management". [2] [3] Other mining companies dismiss concerns by stating that the species is "rare but not on IUCN Red List due to insufficient data", ignoring its disappearance for almost a century and equating "insufficient data" with a licence to act irresponsibly.

Cicada Superfamily of insects

The cicadas are a superfamily, the Cicadoidea, of insects in the order Hemiptera. They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, the Tettigarctidae, with two species in Australia, and the Cicadidae, with more than 3,000 species described from around the world; many species remain undescribed.

Hemiptera Order of insects often called bugs

Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Many insects commonly known as "bugs", especially in American English, belong to other orders; for example, the lovebug is a fly and the May bug and ladybug are beetles.

<i>Vitex agnus-castus</i> Species of flowering plant in the mint family Lamiaceae

Vitex agnus-castus, also called vitex, chaste tree, chasteberry, Abraham's balm, lilac chastetree, or monk's pepper, is a native of the Mediterranean region. It is one of the few temperate-zone species of Vitex, which is on the whole a genus of tropical and sub-tropical flowering plants. Theophrastus mentioned the shrub several times, as agnos (άγνος) in Enquiry into Plants. It has been long believed to be an anaphrodisiac – leading to its name as chaste tree – but its effectiveness for such action remains unproven.

Periodical cicadas Genus of true bugs native to North America

Magicicada is the genus of the 13-year and 17-year periodical cicadas of eastern North America, consisting of seven species. Although they are sometimes called "locusts", this is a misnomer, as cicadas belong to the taxonomic order Hemiptera, suborder Auchenorrhyncha, while locusts are grasshoppers belonging to the order Orthoptera. Magicicada belongs to the cicada tribe Lamotialnini, a group of genera with representatives in Australia, Africa, and Asia, as well as the Americas.

Embioptera Order of insects

The order Embioptera, commonly known as webspinners or footspinners, are a small group of mostly tropical and subtropical insects, classified under the subclass Pterygota. The order has also been called Embiodea or Embiidina. More than 400 species in 11 families have been described, the oldest known fossils of the group being from the mid-Jurassic. Species are very similar in appearance, having long, flexible bodies, short legs, and only males having wings.

The eastern subalpine warbler is a small typical warbler which breeds in the southernmost areas of Europe. It was first described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name Motacilla cantillans. The specific cantillans is Latin for "warbling" from canere, "to sing".

<i>Thopha saccata</i> Australian species of cicada

Thopha saccata, commonly known as the double drummer, is the largest Australian species of cicada and reputedly the loudest insect in the world. Documented by the Danish zoologist Johan Christian Fabricius in 1803, it was the first described and named cicada native to Australia. Its common name comes from the large dark red-brown sac-like pockets that the adult male has on each side of its abdomen—the "double drums"—that are used to amplify the sound it produces.

<i>Massospora cicadina</i> Species of fungus that infects periodical cicadas

Massospora cicadina is a fungal pathogen that infects only 13 and 17 year periodical cicadas. Infection results in a "plug" of spores that replaces the end of the cicada's abdomen while it is still alive, leading to infertility, disease transmission, and eventual death of the cicada.

Machaerotidae Family of true bugs

Machaerotidae are a family of bugs in the superfamily Cercopoidea which were formerly grouped with the other cercopids. They are sometimes called as tube-forming spittle-bugs as the nymphs form a calcareous tube within which they live. These bugs are mainly found in the Old World tropics. The adults of many genera have a long, free and spine-like process originating at the scutellum and thus superficially similar to the tree-hoppers, Membracidae. Its tegmen or forewing, like typical bugs of the suborder Heteroptera, always has a distinct, membranous apical area.

<i>Sphecius grandis</i> Species of wasp

Sphecius grandis, also called the western cicada killer, is a species of cicada killer wasp (Sphecius). The western species shares the same nesting biology as its fellow species, the eastern cicada killer. S. grandis, like all other species of the genus Sphecius, mainly provides cicadas for its offspring. It forms nest aggregations and mates and broods once in a year, in July and early August. The wasp is on average 3 cm (1 in) to 5 cm (2 in) in length and is amber-yellow with yellow rings on its abdomen.

<i>Chremistica ochracea</i> Species of true bug

Chremistica ochracea is a cicada species of the genus Chremistica and suborder Auchenorrhyncha, which includes cicadas, leafhoppers, planthoppers, treehoppers, froghoppers and spittlebugs. They are usually referred to as 'thin winged cicada' in Taiwan and 'peaceful cicada' in China due to their abundance in these areas. They can be identified by their green appearance with thin, greenish, transparent wings and are heavily distributed in China, Taiwan, Japan, India and Malaya. However, there are limited number of scientific papers that describe the characteristics and behaviour of this species in detail.
