Xerces: Hylaeus hula is a small bee endemic to the island of Hawaii in Hawaii. It is superficially similar to H. flavifrons, differing by the narrower yellow- marked scape and other details. Most collection records are from the Kilauea area, and like other dry- mesic species it is now rare.
Insects of Hawaii: Medium-sized bees with clear to slightly smoky wings. Male with unusual face rather flat, yellow clypeus and lower paraocular areas, unusual yellow stripe along lateral edge of scape; pronotum and legs variably marked. Female with narrow, irregular yellow stripe along the eye up to level of antennal sockets; pronotal lobes and sometimes collar marked; supraclypeal area relatively long, about twice as wide as long.
Many collections have females of H. filicum placed with males of H. hula, despite having not been taken together. They may have been associated based on abundance, as specimens of female H. hula and male H. filicum are much less common in these collections.
