Sphecodes Schenckii
''Sphecodes schenckii'' is a solitary cleptoparasitic bee which is found in southern and eastern Europe and the Middle East. Its host is '' Lasioglossum discum'' and possibly ''Halictus simplex'' where ''L. discum'' does not occur such as in southern Germany and Switzerland. It is rare and there are only a few records from each country from which it has been recorded. It prefers warm open areas, such as grasslands and Mediterranean scrub, and may be threatened by reafforestation and vegetation succession. The specific name ''schenckii'' is in honour of the German Hymenopterist Adolph Schenck Adolph Schenck (born 11 April 1803 in Dillenburg, Germany, died February 23, 1878 ) was a German entomologist and teacher. Philipp Adolph Schenck was a son of Judicial Counselor and mining assessor, Johann Jacob Schenck (born May 23, 1763 in Sieg ....

Theodosio De Stefani Perez
Theodosio De Stefani Perez (6 February 1853 in Santa Ninfa, Trapani – 25 February 1935 in Giacalone, Palermo) was an Italian naturalist and entomologist who specialised in Hymenoptera and Diptera. The Via Teodosio De Stefani Perez in Palermo honours him. His collection of Coleoptera is held by the Zoology Museum of the University of Palermo. Biography ''Theodosio De Stefani Perez'' was born in the family castle in Santa Ninfa (Trapani) in southwestern Sicily. He was a son of don Mariano De Stefani Falco and donna Ippolita Perez. He was the fourth of seven children. The father was the scion of a wealthy family of landowners, while the mother was a descendant of the Prince of Carloforte and heir to great wealth, but not the noble title.Riggio, S. 1984Atti del Convegno “l naturalisti e la cultura scientifica siciliana nell '800” pp. 447 – 464, Portr.

Kleptoparasitism
Kleptoparasitism (etymologically, 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, which can mean 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 Kleptoparasitism is a fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lasioglossum Discum
The sweat bee genus ''Lasioglossum'' is the largest of all bee genera, containing over 1700 species in numerous subgenera worldwide.Gibbs, J., et al. (2012)Phylogeny of halictine bees supports a shared origin of eusociality for ''Halictus'' and ''Lasioglossum'' (Apoidea: Anthophila: Halictidae).''Molecular Phylogenetics and Evolution'' 65(3), 926-39. They are highly variable in size, coloration, and sculpture; among the more unusual variants, some are cleptoparasites, some are nocturnal, and some are oligolectic. Most ''Lasioglossum'' species nest in the ground, but some nest in rotten logs. Social behavior among species of ''Lasioglossum'' is extraordinarily variable; species are known to exhibit solitary nesting, primitive eusociality, and social parasitism. Colony sizes vary widely, from small colonies of a single queen four or fewer workers to large colonies of >400 workers and perennial life cycles. The genus ''Lasioglossum'' can be divided ...

Halictus Simplex
The genus ''Halictus'' is a large assemblage of bee species in the family Halictidae. The genus is divided into 15 subgenera, some of dubious monophyly, containing over 200 species, primarily in the Northern Hemisphere (a few species occur in South America, Asia and Africa). Most species are black or dark brown, sometimes metallic greenish-tinted, with apical whitish abdominal bands on the terga (the related genus ''Lasioglossum'', which is otherwise often similar in appearance, has the abdominal hair bands located basally, not apically). Many species in the genus are eusocial, with colony sizes range from very small (two to four bees) to large (>200). Nests are typically burrows in the soil, with several ovoid "cells" in which pollen mixed with nectar is provided as food for the developing larvae; a single egg is laid on a pollen mass, and the cell is sealed. In a few species, the cells are arranged in clusters resembling a honeycomb, but constructed of soil rather than bees ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolph Schenck
Adolph Schenck (born 11 April 1803 in Dillenburg, Germany, died February 23, 1878 ) was a German entomologist and teacher. Philipp Adolph Schenck was a son of Judicial Counselor and mining assessor, Johann Jacob Schenck (born May 23, 1763 in Siegen, Germany, February 14, 1805 in Dillenburg) and Sophie Karoline, b. Jaeckel, from Herborn (Hesse), Herborn (1767-1836). At the age of 9, he suffered a knee injury while playing, which developed into a paralysis of the right leg which meant that he had to use a walking aid for a long time. Despite this disability he was able to collect entomological specimens in the field and amass an important collection, including the discovery of an otherwise Mediterranean species of spider wasp. Schenck attended the Boys' School (''Pädagogium'') in Dillenburg until 1818, then the Grammar School in Weilburg (''Gymnasium Philippinum Weilburg''), where he took the Abitur in 1821. He then studied philology, natural sciences and pedagogy at the University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of Europe
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1882
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
