Taxonomy and phylogeny of the Asphondylia species (Diptera: Cecidomyiidae) of North American goldenrods: challenging morphology, complex host associations, and cryptic speciation
“
The small rosette galls develop only in apical buds and can be locally very common. These galls are composed of several shortened leaves that surround a single central, rigid chamber made of closely attached leaves, and are lined by white mycelium on the inside.
