Sphex Semifossulatus
Wasps of the genus ''Sphex'' (commonly known as digger wasps) are cosmopolitan predators that sting and paralyze prey insects. ''Sphex'' is one of many genera in the old digger wasp family Sphecidae ('' sensu lato''), though most apart from the Sphecinae have now been moved to the family Crabronidae. There are over 130 known ''Sphex'' species. Behaviour In preparation for egg laying, they construct a protected "nest" (some species dig nests in the ground, while others use pre-existing holes) and then stock it with captured insects. Typically, the prey are left alive, but paralyzed by wasp toxins. The wasps lay their eggs in the provisioned nest and the wasp larvae feed on the paralyzed insects as they develop. The great golden digger wasp ('' Sphex ichneumoneus'') is found in North America. The developing wasps spend the winter in their nest. When the new generation of adults emerge, they contain the genetically programmed behaviors required to carry out another season of ...

Sphex Pensylvanicus
''Sphex pensylvanicus'', the great black wasp, is a species of Sphex, digger wasp. It lives across most of North America and grows to a size of . The larvae feed on living insects that the females paralyze and carry to the underground nest. Distribution ''S. pensylvanicus'' is distributed across most of the contiguous United States and northern Mexico. During the late 20th century, its range expanded north to New York (state), New York and the Canadian provinces of Quebec and Ontario. Description ''Sphex pensylvanicus'' is a large, black wasp, significantly larger than their Conspecificity#Congener, congener ''Sphex ichneumoneus'' (the great golden digger wasp). Males are smaller than females, at only long compared with typical female sizes of . According to John Bartram, "The sting of this Wasp is painful, but does not swell like others". As well as being larger than ''S. ichneumoneus'', they are also darker, with smoky wings and an entirely black body, where ''S. ichneumoneus ...

Niko Tinbergen
Nikolaas "Niko" Tinbergen (; ; 15 April 1907 – 21 December 1988) was a Dutch biologist and ornithologist who shared the 1973 Nobel Prize in Physiology or Medicine with Karl von Frisch and Konrad Lorenz for their discoveries concerning the organization and elicitation of individual and social behavior patterns in animals. He is regarded as one of the founders of modern ethology, the study of animal behavior. In 1951, he published ''The Study of Instinct'', an influential book on animal behaviour. In the 1960s, he collaborated with filmmaker Hugh Falkus on a series of wildlife films, including ''The Riddle of the Rook'' (1972) and ''Signals for Survival'' (1969), which won the Italia prize in that year and the American blue ribbon in 1971. Education and early life Born in The Hague, Netherlands, he was one of five children of Dirk Cornelis Tinbergen and his wife Jeannette van Eek. His brother, Jan Tinbergen, won the first Bank of Sweden Prize in Economic Sciences in Memory o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphex Afer
Wasps of the genus ''Sphex'' (commonly known as digger wasps) are cosmopolitan predators that sting and paralyze prey insects. ''Sphex'' is one of many genera in the old digger wasp family Sphecidae (''sensu lato''), though most apart from the Sphecinae have now been moved to the family Crabronidae. There are over 130 known ''Sphex'' species. Behaviour In preparation for egg laying, they construct a protected "nest" (some species dig nests in the ground, while others use pre-existing holes) and then stock it with captured insects.
