Lasioglossum Figueresi, L. Figueresi
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 divid ...

John Curtis (entomologist)
John Curtis (3 September 1791 – 6 October 1862) was an English entomologist and illustrator. Biography Curtis was born in Norwich to Frances and Charles Morgan Curtis. Charles Morgan died before his son had reached the age of 4 years. His mother, Frances, had a passion for flowers and was a professional flower grower. She encouraged her son to study natural history with a young local naturalist, Richard Walker (1791–1870). At the age of 16 John became an apprentice at a local lawyer's office in Norwich but devoted his spare time to studying and drawing insects and, with insect collecting becoming a growing craze, he found he could make a living selling the specimens he found. At this time he became a friend of Simon Wilkin (1790–1862) a wealthy landowner in Norfolk, eventually leaving his job to live with Wilkin at Cossey Hall where the extensive natural history library and specimen collection afforded him the opportunity to study his emerging over-riding passion, entomo ...

Lasioglossum Malachurum
''Lasioglossum malachurum'', the sharp-collared furrow bee, is a small European halictid bee. This species is obligately eusocial, with queens and workers, though the differences between the castes are not nearly as extreme as in honey bees. Early taxonomists mistakenly assigned the worker females to a different species from the queens. They are small (about 1 cm), shiny, mostly black bees with off-white hair bands at the bases of the abdominal segments. ''L. malachurum'' is one of the more extensively studied species in the genus ''Lasioglossum'', also known as sweat bees. Researchers have discovered that the eusocial behavior in colonies of ''L. malachurum'' varies significantly dependent upon the region of Europe in which each colony is located. Taxonomy and phylogeny ''L. malachurum'' was described by the entomologist William Kirby in 1802. This species of bees fall within the genus ''Lasioglossum'', which is the largest bee genus. ''Lasioglossum'' falls within the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dialictus
''Dialictus'' is a subgenus of sweat bees belonging to the genus '' Lasioglossum''. Most of the members of this subgenus have a metallic appearance, while some are non-metallic. There are over 630 species worldwide. They are commonly found in the Northern Hemisphere The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's Nort ... and are found in abundance in North America. Members of this subgenus also have very diverse forms of social structure making them model organisms for studying the social behavior of bees. Morphology Members of ''Lasioglossum (Dialictus)'' are small, about 3.4–8.1 mm in size, and distinguished from other halictids by a strongly arched basal vein and weakened distal veins on the forewings. Distinguishing between some of the species in ''Lasioglossum (Dialictus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
