What specific habitat types are frequently cited as essential locations for endangered Oahu Hylaeus species like *Hylaeus anthracinus*?
Answer
Dry forests and shrublands
The survival of native Hawaiian *Hylaeus* species is inextricably linked to the preservation of specific, intact native plant communities that provide necessary nectar and pollen resources. For species confirmed on Oahu, particularly *Hylaeus anthracinus*, the preferred ecological zones are consistently identified as the dry forests and shrublands. These habitats, found across different ecological zones on the island, offer the specific floral resources these bees rely upon. This preference means that areas characterized by intensive human development or large-scale farming often lack the necessary environmental integrity to support viable populations of these at-risk native pollinators.
