Asphondylia eupatorii
Asphondylia eupatorii is a species of gall midge in the family Cecidomyiidae, first described by Felt in 1911. The species is known to induce galls on its host plant Ageratina altissima (white snakeroot). Like other members of the genus Asphondylia, this species likely manipulates plant tissue to form protective galls that serve as both shelter and food source for the developing larvae. The genus Asphondylia is notable for inducing galls on a variety of plant species, with some species showing highly specific host associations.
