Gynanisa Maja
''Gynanisa maja'', the speckled emperor or chipumi, is a moth of the family Saturniidae. The species was first described by Johann Christoph Friedrich Klug in 1836. It is known from South Africa to eastern Africa (up to Angola and Zambia). ''Gynanisa nigra'' is just a darker form and not a distinct species. The wingspan is 105–113 mm. Adults are on wing from late December to early February. Larvae have been recorded on '' Acacia erioloba'', '' Acacia karroo'', '' Acacia mollissima'', '' Berlinia paniculata'', '' Brachystegia venosa'', '' Cassia'', ''Colophospermum mopane'', '' Elephantorrhiza burchelli'', ''Julbernardia'', ''Laburnum'', '' Peltophorum'', ''Prunus persica'', ''Pterocarpus'', ''Quercus gambelii'', ''Quercus robur'', '' Quercus turneri'', ''Robinia pseudoacacia'' and ''Schotia''. Early instar larvae are gregarious. They have a reddish-black colour. As they develop, they become solitary feeders, hiding on the underside of leaf stems and twigs. These later inst ...

Johann Christoph Friedrich Klug
Johann Christoph Friedrich Klug (5 May 1775, in Berlin – 3 February 1856, in Berlin), was a German entomologist. He described the butterflies and some other insects of Upper Egypt and Arabia in Christian Gottfried Ehrenberg and Wilhelm Friedrich Hemprich's ''Symbolæ Physicæ'' (Berlin, 1829–1845). He was professor of medicine and entomology in the University of Berlin (known in the present day as the Humboldt University of Berlin) where he curated the insect collections from 1810 to 1856. At the same time he directed the Botanic Garden in Berlin which contains his collections. Klug worked mainly on Hymenoptera and Coleoptera. The plant genus '' Klugia'' (now called '' Rhynchoglossum'', Family Gesneriaceae) was named in his honour as well as the butterflies ''Geitoneura klugii'' and '' Heliophisma klugii''. In 1855, he was elected a foreign member of the Royal Swedish Academy of Sciences. Works (Partial List) * Die Blattwespen nach ihren Gattungen und Arten zusammengestellt. ...

Laburnum
''Laburnum'', sometimes called golden chain or golden rain, is a genus of two species of small trees in the subfamily Faboideae of the pea family Fabaceae. The species are '' Laburnum anagyroides''—common laburnum and '' Laburnum alpinum''—alpine laburnum. They are native to the mountains of southern Europe from France to the Balkans. Some botanists include a third species, ''Laburnum caramanicum'', but this native of southeast Europe and Anatolia is usually treated in a distinct genus ''Podocytisus'', more closely allied to the ''Genisteae'' (brooms). Description The ''Laburnum'' trees are deciduous. The leaves are trifoliate, somewhat like a clover; the leaflets are typically long in ''L. anagyroides'' and long in ''L. alpinum''. They have yellow pea-flowers in pendulous leafless racemes long in spring, which makes them very popular garden trees. In ''L. anagyroides'', the racemes are long, with densely packed flowers; in ''L. alpinum'' the racemes are long, but wit ...

Moths Of Africa
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establis ...

Saturniinae
The Saturniinae or saturniines are a subfamily of the family Saturniidae. They are commonly known as emperor moths or wild silk moths. They are easily spotted by the eyespots on the upper surface of their wings. Some exhibit realistic eye-like markings, whilst others have adapted the eyespots to form crescent moon or angular shapes or have lost their wing scales to create transparent windows. They are medium to very large moths, with adult wingspans ranging from 7.5 to 15 cm, in some cases even more. They consist of some of the largest sized Lepidoptera, such as the luna moth, atlas moth, and many more. The Saturniinae is an important source of wild silk and human food in many different cultures. The saturniine genera, approximately 169 in number, are divided into four major and one minor ( Micragonini) tribes. The genus '' Adafroptilum'' presently consists of a group of species with undetermined relationships. Adults in the Saturniinae typically live about 5–12 days ...

Entomophagy
Entomophagy (, from Greek ἔντομον ', 'insect', and φαγεῖν ', 'to eat') is the practice of eating insects. An alternative term is insectivory. Terms for organisms that practice entomophagy are ''entomophage'' and ''insectivore''. Entomophagy is sometimes defined to also include the eating of arthropods other than insects, such as arachnids and myriapods; eating arachnids may also be referred to as arachnophagy. In non-humans Entomophagy is widespread among many animals, including non-human primates. Animals that feed primarily on insects are called insectivores. Insects, nematodes and fungi that obtain their nutrition from insects are sometimes termed ''entomophagous'', especially in the context of biological control applications. These may also be more specifically classified into predators, parasites or parasitoids, while viruses, bacteria and fungi that grow on or inside insects may also be termed ''entomopathogenic'' (see also entomopathogenic fungi). ...

Gregarious
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators selected this behavior in wasps of the family Vespidae. This wasp behaviour evidences the most fundamental characteristic of animal sociality: parental investment. Parental investment is any expenditure of resources (time, energy, social capital) to benefit one's offspring. Parental investment detracts from a parent's capacity to invest in future reproduction and aid to kin (including other offspring). An animal that cares for its young but shows no other sociality traits is said to be ''subsocial''. An animal that exhibits a high degree of sociality is called a ''social animal''. The highe ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Robinia Pseudoacacia
''Robinia pseudoacacia'', commonly known in its native territory as black locust, is a medium-sized hardwood deciduous tree, belonging to the tribe Robinieae of the legume family Fabaceae. It is endemic to a few small areas of the United States, but it has been widely planted and naturalized elsewhere in temperate North America, Europe, Southern Africa and Asia and is considered an invasive species in some areas. Another common name is false acacia, a literal translation of the specific name (''pseudo'' reek ''ψευδο-''meaning fake or false and ''acacia'' referring to the genus of plants with the same name). Description Black locust reaches a typical height of with a diameter of . It is a very upright tree with a straight trunk and narrow crown that grows scraggly with age. The dark blue-green compound leaves with a contrasting lighter underside give this tree a beautiful appearance in the wind and contribute to its grace. Black locust is a shade-intolerant species and ...

Quercus Turneri
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably ''Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Man ...

Quercus Gambelii
''Quercus gambelii'', with the common name Gambel oak, is a deciduous small tree or large shrub that is widespread in the foothills and lower mountains of western North America. It is also regionally called scrub oak, oak brush, and white oak. The common and scientific names, Gambel oak and ''Quercus gambelii'', were named after the American naturalists, naturalist William Gambel (1821–1849). Description ''Quercus gambelii'' trees differ in size from one location to another. The average mature height is from , but occasionally reaches heights of in some locations. Dwarf stands of plants under tall are common in marginal areas where heavy browsing occurs. The largest trees are found in the southern range of the species along streams. These trees reach up to 100 feet tall. The champion tree is in Arizona at tall. Although the wood is hard and dense, its branches are irregular and crooked, making them flexible enough to bend without breaking when covered with heavy sno ...
