Galls on Rudbeckia laciniata 'Herbstsonne' flowers - Asphondylia rudbeckiaeconspicua
Beavercreek, Greene County, Ohio, USA August 9, 2019
Might these galls on the flowers of Rudbeckia laciniata 'Herbstsonne' be caused by the midge Asphondylia rudbeckiaeconspicua? This is the first time I have noticed such galls on this plant, in the two decades it has dwelt in my garden.
