Cliff Mining Bee

The Cliff Mining Bee, Andrena species in the family Andrenidae, is a solitary ground-nesting bee that excavates tunnels in cliff faces, earthen banks, and compacted sandy or loamy soils, where the loose or friable substrates exposed in cliff profiles provide ideal nesting conditions. Mining bees in the genus Andrena are among the most species-rich solitary bee genera in the world, with hundreds of species across the Holarctic region, many narrowly specialized in their choice of pollen host plants. Female cliff mining bees construct vertical or angled burrows in cliff faces, with lateral cells off the main shaft, each containing a pollen ball and a single egg. Males are typically smaller and emerge before females to establish territories near nesting sites. Many Andrena species are oligolectic, collecting pollen from only a small number of plant species, making their populations sensitive to the availability of specific flowering plants in the landscape surrounding nesting areas. Cliff and bank nesting habitats provide well-drained, sun-warmed substrates essential for brood development. The loss of natural cliff faces and earthen banks to development, vegetation succession, and quarrying reduces available nesting habitat for cliff mining bees.

Common Furrow Bee

<em>Lasioglossum calceatum</em>, commonly known as the common furrow bee, is a eusocial bee in the family Halictidae. The species has been documented in Belgium, Denmark, Luxembourg, Norway, and Sweden, and its range extends broadly across Europe and parts of Asia. Furrow bees in the genus <em>Lasioglossum</em> are among the most diverse groups of bees, and <em>L. calceatum</em> is one of the more commonly encountered halictid species in temperate European habitats. The species typically inhabits a variety of open and semi-open landscapes including grasslands, meadows, gardens, and woodland edges, nesting in the ground. It is assessed as Least Concern, consistent with its wide European distribution. <em>Lasioglossum calceatum</em> is a generalist forager, visiting a broad range of flowering plants for pollen and nectar, and thus contributes to pollination services in diverse habitats. Biological traits of this species remain poorly documented in the scientific literature. Colonies are typically small and primitively eusocial, with a single foundress queen and worker offspring, making this species of interest for studies of the evolution of sociality in bees.
