Dolichovespula Omissa
''Dolichovespula omissa'' is a species of wasp in the family of Vespidae. It lives as a social parasite by letting colonies of ''Dolichovespula sylvestris'' raise their young. The wasps reach a body length of 15 to 18 millimeters (females) or 14 to 16 millimeters (males). Their yellow-black pattern is hardly variable. The males can only be distinguished from the other species of the genus ''Dolichovespula'' by details of the genital capsule. Occurrence The species occurs from the northern parts of southern Europe to southern Scandinavia and Turkey. It inhabits various open habitats, light forests, and forest margins. It is rare in Central Europe. It flies from mid-June to early September. Young animals of the new generation fly from mid-July onward. Naming In other languages common names exist for the species that highlight the social parasitism lifestyle by referencing the cuckoo Cuckoos are birds in the Cuculidae family, the sole taxon in the order Cuculiformes .

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.

Vespidae
The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as ''Polistes fuscatus'', '' Vespa orientalis'', and '' Vespula germanica'') and many solitary wasps. Each social wasp colony includes a queen and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter. New queens and males (drones) are produced towards the end of the summer, and after mating, the queens hibernate over winter in cracks or other sheltered locations. The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines). Many species are pollen vectors contributing to the pollination of several plants, being potential or even effective pollinators, while others are notable predators of pest insect species. The ...

Social Parasitism (biology)
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

Dolichovespula Sylvestris
The tree wasp (''Dolichovespula sylvestris'') is a species of eusocial wasp in the family Vespidae, found in the temperate regions of Eurasia, particularly in western Europe. Despite being called the tree wasp, it builds both aerial and underground paper nests, and can be found in rural and urban habitats. ''D. sylvestris'' is a medium-sized wasp that has yellow and black stripes and a black dot in the center of its clypeus. It is most common to see this wasp between May and September during its 3.5 month colony cycle. Tree wasps carry out worker policing and have a haplodiploid sex-determination system; this results in a high level of relatedness within the colony. The workers will take over all of the foraging from the queen once the first workers reach adulthood. Worker wasps typically forage for other insects, the nectar of plants, and wood to digest for nest construction. The tree wasp is sometimes a victim of the nest parasite ''Dolichovespula omissa, ''who lays their eggs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolichovespula
''Dolichovespula'' is a small genus of social wasps distributed widely throughout the Northern Hemisphere. The yellow and black members of the genus are known by the common name yellowjackets in North America, such as '' Dolichovespula norwegica'', along with members of their sister genus ''Vespula''. In a study on the nesting biology of ''Dolichovespula'', a colony of '' D. maculata'' with 771 workers was reported as having the largest recorded population count. Overview Several morphological differences distinguish them from ''Vespula''. The most noticeable is the long face (''dolikhos'' = "long" in Greek). Viewed from the front, ''Dolichovespula'' faces are long, while ''Vespula'' faces are short and round. The oculomalar space, the distance between the eye and the mandible, is long in ''Dolichovespula'' and short in ''Vespula''. ''Dolichovespula'' nests are usually aerial, while ''Vespula'' spp. often nest underground. Reproduction All females are born with reproductive c ...

Cuckoo
Cuckoos are birds in the Cuculidae family, the sole taxon in the order Cuculiformes . The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae respectively. The cuckoo order Cuculiformes is one of three that make up the Otidimorphae, the other two being the turacos and the bustards. The family Cuculidae contains 150 species which are divided into 33 genera. The cuckoos are generally medium-sized slender birds. Most species live in trees, though a sizeable minority are ground-dwelling. The family has a cosmopolitan distribution; the majority of species are tropical. Some species are migratory. The cuckoos feed on insects, insect larvae and a variety of other animals, as well as fruit. Some species are brood parasites, laying their eggs in the nests of other species and giving rise to the metaphor ''cuckoo's egg'' ...
