What specific federally listed endangered *Hylaeus* species is highlighted as an example of vulnerability?
Answer
*Hylaeus finitimus*
The text explicitly points to *Hylaeus finitimus* as a stark example illustrating the vulnerability inherent in high specialization among native Hawaiian bees. This species faces severe pressure not only from habitat loss affecting its required native flora but also from novel threats like introduced predatory insects. The listing of this species, along with others, under the Endangered Species Act by the U.S. Fish and Wildlife Service acknowledges that the loss of these unique evolutionary branches would represent an irreversible void in the native Hawaiian ecosystem.
