Sphecodopsis Sp, Sandveld, 2012
''Sphecodopsis'' is a genus of cleptoparasitic "cuckoo" bees in the family Apidae. Endemic to southern Africa, the wasp-like bees of this genus are generally small, varying from in length, and mostly black, with orange-ish or reddish colouring of the metasoma in some of the species. The bee genus '' Scrapter'' is recognised as a host for the cleptoparasitic life cycle of some ''Sphecodopsis'', but further data regarding preferred hosts is not available for most of the species. Taxonomy German entomologist Hans Bischoff first described the genus in 1923 in the work "Kenntnis afrikanischer Schmarotzerbienen", published in the ''Deutsche entomologische Zeitschrift''. The genus name is Greek for "wasp-like", with "spheco-" meaning wasp. Of the fourteen currently recognised species, several of them were originally described under a different genus and have subsequently been included in ''Sphecodopsis''. Some of the species in the genus are generally still poorly defined, owing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Bischoff
Hans Bischoff (30 November 1889 – 18 March 1960) was a German entomologist from Berlin. He was Kustos or curator of Hymenoptera (and Neuropterida The Neuropterida are a clade, sometimes placed at superorder level, of holometabolous insects with over 5,700 described species, containing the orders Neuroptera (lacewings, antlions), Megaloptera (alderflies, dobsonflies), and Raphidioptera (sna ...) at Museum für Naturkunde (Berlin) from 1921 until 1955. He went to the Netherlands to take the Wasmann Collection of ants during World War II in order to take them to the Berlin museum. Selected works *''Biologie der Hymenopteren.

Hemimeris
''Hemimeris'' is a genus of flowering plants in the family Scrophulariaceae, native to the Cape Provinces of South Africa. They secrete oils to attract specialized oil-collecting bees from the genus '' Rediviva''.

Senecio
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helichrysum
The genus ''Helichrysum'' consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is '' Helichrysum orientale''. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Anicent Greek words (helios, sun) and (, gold). It occurs in Africa (with 244 species in South Africa), Madagascar, Australasia and Eurasia. The plants may be annuals, herbaceous perennials or shrubs, growing to a height of . The genus was a wastebasket taxon, and many of its members have been reclassified in smaller genera, most notably the Everlastings, now in the genus ''Xerochrysum''. Their leaves are oblong to lanceolate. They are flat and pubescent on both sides. The bristles of the pappus are scabrous, barbellate, or plumose. The receptacle (''base of the flower head'') is often smooth, with a fringed margin, or honey-combed, and resemble daisies. They may be in almost all colors, except blue. There are ...

Grielum
''Grielum'' is a genus of four accepted species of plants in the family Neuradaceae. They are low-growing annual herbs endemic to dry regions, mainly in Western South Africa and Namibia. Description The genus comprises annual dwarf herbs with pronounced taproots. * The leaves are more or less furry, and may be canescent or tomentose. They are lobed at least, but more typically are decompound. The stipules are obsolete, being barely evident if present at all. * The flowers are conspicuous and are borne on singly on pedicels in leaf axils. They are generally vivid lemon-yellow in colour, but with a white centre in some species. The calyx has five sepals, forming a shallow cup. The corolla has five petals, usually imbricate and thereby forming a shallow bowl, though this is less evident if the petals happen to be narrow, as sometimes occurs on a particular plant. The petals are inserted into the throat of the calyx cup. There are ten stamens, more or less set in two whor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operculum (animal)
An operculum is an anatomical feature, a stiff structure resembling a lid or a small door that opens and closes, and thus controls contact between the outside world and an internal part of an animal. Examples include: * An operculum (gastropod), a single lid that (in its most complete form) closes the aperture of the shell when the animal is retracted, and thus protects the internal soft parts of the animal that are not completely covered by the shell. The operculum lies on the top rear part of the foot. When the foot is retracted, the operculum is rotated 180° and closes the shell. * An operculum (fish), a flap that covers the gills in bony fishes and chimaeras. * The cover that rapidly opens a cnida of a cnidarian such as a jellyfish or a sea anemone. The lid may be a single hinged flap or three hinged flaps arranged like slices of pie. * In insects, the operculum is the name for one or more lids covering the tympanal cavity. A subgenital operculum is exhibited in phasmoidea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
