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.

Coast Purple Tip

Coast purple-tip (Colotis erone) is a butterfly in the family Pieridae, subfamily Colotinae, native to coastal and wooded savanna habitats of sub-Saharan Africa, occurring in eastern and southern Africa from Kenya and Tanzania south to Mozambique and South Africa. Like other Colotis species, males have striking wing-tip markings—in this case a vivid purple or lilac patch on the forewing apex—while females are more cryptically patterned. Larvae feed on plants in the family Salvadoraceae or Capparaceae, typical host families for the genus. Adults are fast-flying and typically found along woodland margins, coastal thickets, and scrub habitats near the coast. The genus Colotis is distributed across Africa and Asia, with many species restricted to specific host plants and habitat types. Coast purple-tip is assessed as Least Concern by the IUCN, with populations distributed across suitable coastal and woodland habitat in eastern and southern Africa. Like many invertebrates, it is sensitive to habitat quality and the availability of its larval food plants.
