Stizina
The Stizina is a subtribe of small to large-sized sand wasps in the tribe Bembicini The Bembicini, or sand wasps, are a large tribe of bembicid wasps, comprising 20 genera. Bembicines are parasitoids on various groups of insects. The type of prey captured tends to be rather consistent within each genus, with flies (Diptera) b .... The subtribe is distinguished primarily by features of wing venation. Members of the genus '' Stizus'' are large, and superficially resemble cicada-killer wasps (genus '' Sphecius'', in the related subtribe Spheciina), and members of the genus '' Stizoides'' are cleptoparasites in the nests of other Crabronids.

Bembicini
The Bembicini, or sand wasps, are a large tribe of bembicid wasps, comprising 20 genera. Bembicines are parasitoids on various groups of insects. The type of prey captured tends to be rather consistent within each genus, with flies (Diptera) being the most common type of prey taken. Nests are typically short, simple burrows, with a single enlarged chamber at the bottom which is stocked with freshly paralysed prey items for the developing wasp larva; the egg may sometimes be laid before the chamber is completely stocked. It is common for numerous females to excavate nests within a small area where the soil is suitable, creating large and sometimes very dense nesting aggregations, which tend to attract various species of parasitic flies and wasps, many of which are cleptoparasites; in some cases, the sand wasps prey on their own parasites (e.g.,), a surprisingly rare phenomenon in the animal kingdom. Although sand wasps are normally yellow and black, some are black and white with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stizus
''Stizus'' is a genus of sand wasps belonging to the family Bembicidae. There are over 100 species. These wasps can reach a length of about . They are yellow and black, rarely reddish. Species within this genus can be found in Europe, in Africa, and in North America. European species Species within this genus include: *''Stizus aestivalis'' Ricardo García Mercet, Mercet, 1906 *''Stizus annulatus'' (Johann Christoph Friedrich Klug, Klug, 1845) *''Stizus bipunctatus'' (Frederick Smith (entomologist), Smith, 1856) *''Stizus continuus'' (Klug, 1835) *''Stizus fasciatus'' (Johan Christian Fabricius, Fabricius, 1781) *''Stizus hispanicus'' Alexander Mocsáry, Mocsary, 1883 *''Stizus perrisi'' Léon Jean Marie DuFour, DuFour, 1838 *''Stizus pubescens'' (Klug, 1835) *''Stizus ruficornis'' (Forster, 1771) *''Stizus rufipes'' (Fabricius, 1804) *''Stizus tricolor'' Anton Handlirsch, Handlirsch, 1892 See also * List of Stizus species References *Manfred Blösch: Die Grabwespen Deu ...

Sphecius
Cicada killer wasps (genus ''Sphecius'') are large, solitary, ground-dwelling, predatory wasps. They are so named because they hunt cicadas and provision their nests with them, after stinging and paralyzing them. Twenty-one species worldwide are recognized. The highest diversity occurs in the region between North Africa and Central Asia. In North America, the term "cicada killer wasp" usually refers to the most well-known species, the eastern cicada killer (''S. speciosus''). A few other related genera also are sometimes referred to as "cicada killers", e.g. '' Liogorytes'' in South America and '' Exeirus'' in Australia. The use of cicadas as prey is in keeping with the typical behavior of the tribe Bembicini, which tend to specialize on various members of the Cicadomorpha as prey items. Species This list of species is probably complete as of March 31, 2009. It has been adapted from thCatalog of ''Sphecius'' species(California Academy of Sciences). Notable subspecies are also ...

Cleptoparasite
Kleptoparasitism (originally spelt clepto-parasitism, meaning "parasitism by theft") is a form of feeding in which one animal deliberately takes food from another. The strategy is evolutionarily stable when stealing is less costly than direct feeding, such as when food is scarce or when victims are abundant. Many kleptoparasites are arthropods, especially bees and wasps, but including some true flies, dung beetles, bugs, and spiders. Cuckoo bees are specialized kleptoparasites which lay their eggs either on the pollen masses made by other bees, or on the insect hosts of parasitoid wasps. They are an instance of Emery's rule, which states that insect social parasites tend to be closely related to their hosts. The behavior occurs, too, in vertebrates including birds such as skuas, which persistently chase other seabirds until they disgorge their food, and carnivorous mammals such as spotted hyenas and lions. Other species opportunistically indulge in kleptoparasitism. Strategy K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bembicidae
The Bembicidae comprise a large family of apoid wasps that includes over 80 genera and over 1800 species which have a worldwide distribution. They excavate nests in the soil, frequently in sandy soils, and store insects of several orders, for example Diptera, Orthoptera, Hemiptera, Lepidoptera and Odonata in the burrows. Some species are kleptoparasites of other Bembicidae. The different subgroups of Bembicidae are each quite distinctive, and rather well-defined, with clear morphological and behavioral differences between them. Taxonomy and phylogeny Bembicids were originally a part of a single large family, the Sphecidae The Sphecidae are a Cosmopolitan distribution, cosmopolitan family of wasps of the suborder Apocrita that includes Ammophilinae, sand wasps, mud daubers, and other thread-waisted wasps. The name Sphecidae was formerly given to a much larger g ..., then for many years were treated as a separate family, and recently have been placed back into a larger fam ...

Insect Subtribes
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
