Lasioglossum malachurum ist eine europäische Bienenart aus der Gattung Lasioglossum, im deutschen wird sie Pförtner-Schmalbiene oder Feldweg-Schmalbiene genannt.
Lasioglossum malachurum ist eine kleine, dunkel gefärbte Biene, die in Nordafrika, Eurasien und Deutschland verbreitet ist. Sie baut ihre Nester im Boden, vor allem in Löss- und Lehmgebieten, und bildet oft Aggregationen von mehreren hundert oder tausend Nestern. Die Art lebt eusozial und überwintert gemeinsam, bevor sie im April ein neues Nest gründet. Die Bienen sammeln Pollen von verschiedenen Pflanzenfamilien und werden von verschiedenen Parasiten wie Kuckucksbienen und Fliegen befallen.
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.
The summary provided discusses various aspects of Lasioglossum malachurum, a species of bees. It describes the taxonomy and phylogeny of L. malachurum, including its classification within the genus Lasioglossum and family Halictidae. The distribution and habitat of L. malachurum are discussed, highlighting its presence in England, continental Europe, and northern Africa, and the impact of different climates on its social behavior. The colony cycle of L. malachurum is explained, detailing the actions of the queen, construction of brood cells, and emergence of workers and reproductive individuals. The pollination behavior of L. malachurum is also mentioned, emphasizing its importance in pollinating plants used by humans.
