Buff-tailed Mining Bee

The Buff-Tailed Mining Bee (Andrena humilis) is a species in the genus Andrena. It is currently classified as Extinct on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Common Dart

<em>Andronymus caesar</em>, known as the common dart, is a butterfly belonging to the family Hesperiidae. This species occupies terrestrial and freshwater habitats, though its specific geographic range is not well characterized in current biodiversity databases. Like other members of the genus Andronymus, <em>Andronymus caesar</em> is likely associated with open woodland, savanna, and grassland ecosystems typical of sub-Saharan Africa, where many related hesperiid species are found. Adults typically exhibit rapid, darting flight patterns and are often observed perching on low vegetation or feeding on flower nectar. Larvae of closely related species are generally known to feed on grasses and related monocots, though host plant preferences specific to <em>Andronymus caesar</em> have not been thoroughly detailed in the available scientific literature. The species is assessed as Least Concern, indicating that no significant population declines or major threats have been identified. Biological traits of this species remain poorly documented, and detailed ecological and life history research would contribute substantially to understanding this taxon.
