Collared Titi

The Collared Titi, known scientifically as <em>Cheracebus torquatus</em>, is a small New World monkey belonging to the family Pitheciidae. <em>Cheracebus torquatus</em> is characterised by its typically dense, soft fur and a pale or white collar or band around the neck and throat region, which gives the species its common and scientific names. Titi monkeys are generally arboreal and highly social, typically living in small family groups occupying territories in forested habitats. They are known for their distinctive pair-bonding behaviour and loud territorial vocalisations. The species inhabits diverse terrestrial and aquatic ecosystems. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Titi is currently assessed as Least Concern on the IUCN Red List.

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.
