What is the evolutionary lineage significance of *Hylaeus* being the only native bees in Hawaii?
Answer
They represent the entire native bee heritage of the islands, demonstrating massive success from a single founder population
The fact that the *Hylaeus* genus comprises the entirety of the native bee heritage in the Hawaiian Islands underscores their monumental evolutionary success. A tiny ancestral founder population managed to arrive, survive the immense selective pressures of a novel tropical/subtropical environment, and diversify into over 100 species. This situation highlights an ecological canvas where few, if any, competitors were present, allowing this single lineage to radiate and fill every available native bee niche across various elevations and floral associations throughout the archipelago over millennia.
