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.

Ensifer arboris is a Gram-negative, nitrogen-fixing bacterium forming effective root nodules on leguminous trees in arid and semi-arid regions of Africa and Asia. It inhabits the rhizosphere and root nodules of Prosopis and other acacia-like leguminous trees in tropical and subtropical environments. This bacterium converts atmospheric nitrogen into biologically available ammonia for its host trees.
