Rhagoletis mendax has often been confused with R. pomonella. It is separated from R. pomonella by the absence of dark markings on the fore femora and the shorter aculeus. Host data may also be useful in diagnosing these species from each other, as R. pomonella has not been recorded from Ericaceae host plants.
