Colletid bee

<em>Hylaeus pictipes</em>, commonly known as the Colletid bee, is a species belonging to the genus <em>Hylaeus</em> within the family Colletidae, one of the most ancient lineages of bees. This species is classified as Extinct, signifying that no living individuals are known to survive. Historical records indicate its former presence across several European countries, including Belgium, Denmark, Luxembourg, Norway, and Sweden. The species is noted to have been capable of occupying virtually all terrestrial and freshwater habitats, suggesting considerable ecological flexibility during its existence. Colletid bees in this genus are typically solitary, with females provisioning individual nest cells with a mixture of pollen and nectar rather than collectively forming colonies. Specific dietary information for <em>Hylaeus pictipes</em> beyond general nectivory and pollen collection has not been recorded. Biological traits of this species remain poorly documented in the scientific literature. The loss of this species reflects broader declines in native bee diversity across Europe, driven by habitat loss, agricultural intensification, and other anthropogenic pressures.
