"Revision of the metallic Lasioglossum (Dialictus) of eastern North America (Hymenoptera: Halictidae: Halictini)". 1 They are generally green or blue, especially the head and thorax. Unlike other sweat bees, they are not attracted to human sweat. They are members of the family of bees known as Halictidae. ![]() 2011.ĭiscover Life bee species guide and world checklist (Hymenoptera: Apoidea: Anthophila). The genus Agapostemon (literally ' stamen loving') is a common group of Western Hemisphere sweat bees. Molecular Phylogenetics and Evolution 65(3), 926-39. Phylogeny of halictine bees supports a shared origin of eusociality for Halictus and Lasioglossum (Apoidea: Anthophila: Halictidae). Two of the better-known species are the European Lasioglossum malachurum and the North American species Lasioglossum zephyrus. Subgeneric classification of Lasioglossum remains controversial, with disagreement among experts on the number and extent of subgenera. Hemihalictus series: Acanthalictus, Austrevylaeus, Biennilaeus, Capalictus, Dialictus, Eickwortia, Evylaeus, Hemihalictus, Rostrohalictus, Pyghalictus, Sphecodogastra. str., Leuchalictus, Oxyhalictus, Parasphecodes, Pseudochilalictus, Rubrihalictus, Urohalictus. Lasioglossum series: Australictus, Callalictus, Chilalictus, Ctenonomia, Echthralictus, Glossalictus, Homalictus, Ipomalictus, Lasioglossum s. Subgenera Ī list of subgenera (modified from Michener's Bees of the World): marginatum, which forms perennial colonies lasting five or six years, with hundreds of workers this species is the only halictine bee with perennial colonies. Eusocial species may have small colonies with only one or a few workers or large colonies with dozens of workers. The Hemihalictus series is composed of species which are solitary, communal, primitively eusocial, cleptoparasitic, or socially parasitic. The Hemihalictus series (or weak-veined Lasioglossum) includes species with a wide range of sociality. aegyptiellum show signs of division of labour indicative of eusociality. The Lasioglossum series (or strong-veined Lasioglossum) is mostly composed of solitary or communal species, even if some species like L. The genus Lasioglossum can be divided into two informal series based on the strength of the distal veins of the forewing. Colony sizes vary widely, from small colonies of a single queen and four or fewer workers to large colonies of >400 workers and perennial life cycles. Social behavior among species of Lasioglossum is extraordinarily variable species are known to exhibit solitary nesting, primitive eusociality, and social parasitism. Most Lasioglossum species nest in the ground, but some nest in rotten logs. They are highly variable in size, coloration, and sculpture among the more unusual variants, some are cleptoparasites, some are nocturnal, and some are oligolectic. ![]() The sweat bee genus Lasioglossum is the largest of all bee genera, containing over 1800 species in numerous subgenera worldwide. ![]()
