• Asteromyia

  Asteromyia is a genus of gall midges comprising approximately nine described species. Members of this genus induce distinct gall morphologies on host plants in the Asteraceae family, particularly Solidago (goldenrod) species. The genus is notable for complex ecological interactions, including obligate mutualisms with symbiotic fungi that form protective gall structures and mediate defense against parasitoids. Some species complexes exhibit incipient adaptive radiation with sympatric sibling species producing phenotypically distinct galls on the same host plant.
