Emergence records for three species of Drosophila breeding in the stinkhorn (Phallus impudicus) are presented. These are D. phalerata, D. subobscura and D. cameraria. The numbers of stinkhorn present in one woodland (0.114 km2) have been estimated for a two-year period. In 1976, the total number of these fungal breeding sites during the summer was approximately 8000 and in 1977 it was 5300. Utilizing the estimates of breeding site numbers, Drosophila emergence data and estimates of adult survival from laboratory populations, density estimates for D. phalerata and D. subobscura are calculated.
