Taxonomy and phylogeny of the Asphondylia species (Diptera: Cecidomyiidae) of North American goldenrods: challenging morphology, complex host associations, and cryptic speciation
“
Leaf snap galls were observed once during this study on S. nemoralis, but we were unable to rear adults from them or to characterize them with molecular tools. Similar galls may be found on other Solidago hosts but the identity of the species that induce them requires further study.
