Asphondylia conspicua
Asphondylia rudbeckiae conspicua
The gall of this species is found on Rudbeckia triloba and Rudbeckia laciniata. The adult and gall were described by Osten Sacken and the gall is figured here for the first time. I have taken it in the valley of the Black Mountains, North Carolina, in August, and have also received it from Miss Alberta Field from Ashtabula, Ohio. The adults emerge late in August and early in September.
