Chocolate Mining Bee

The Chocolate Mining Bee (Andrena carantonica) is a medium-sized solitary bee in the family Andrenidae, native to Europe and extending across temperate Eurasia. Mining bees of the genus Andrena are ground-nesting bees that excavate burrows in soft or sandy soils, creating underground cells provisioned with pollen and nectar as larval food. Andrena carantonica is one of several spring-emerging Andrena species associated with fruit trees and spring-flowering plants; females frequently visit the flowers of apple, cherry, hawthorn, willow, and other early-season species, making them important pollinators of both wild plants and orchard crops. The species is often an early-season visitor alongside other spring bees, making it an important pollination service provider before managed honeybee colonies are at full strength. Males typically emerge before females, patrolling host plant patches in search of mates. The species is eusocial in the broad sense, with females sometimes nesting in loose aggregations in favoured soil sites. The IUCN classifies Andrena carantonica as Least Concern; it is one of the more widespread and frequently recorded Andrena species across its range. Threats to mining bee populations generally include loss of nesting habitat (bare ground), loss of floral resources through agricultural intensification, and pesticide use.

Common Big-eared Bat

The common big-eared bat (<em>Micronycteris microtis</em>) is a small insectivorous bat belonging to the family Phyllostomidae, native to tropical and subtropical regions of South America. Its range includes Colombia and Venezuela, where it typically inhabits diverse terrestrial and aquatic environments including forests and riparian zones. It is classified as Least Concern on the IUCN Red List, indicating a relatively stable population. As its common name suggests, <em>Micronycteris microtis</em> is distinguished by notably large ears relative to its body size, which enhance its echolocation capabilities for detecting prey and navigating complex forest environments. The species is often associated with lowland and foothill forests, roosting in caves, hollow trees, and dense vegetation. It typically feeds on insects and may also consume small vertebrates or fruit on occasion. Biological traits of this species remain poorly documented in the scientific literature.
