A new species of sarcophagid, Colcondamyia auditrix, is described, which locates its cicada host by sound. The fly was shown to respond to the mating song of the male cicada, and the majority of parasitized cicadas were male. Parasitism of females oc

Several species of entomophthoraceous fungi have been reported infecting potato-infesting aphids in Maine (Patch 1907, Shands et al. 1962, 1963, 1972), but their impact on the populations has been variable (Shands et al. 1958). Because these fungi ha
