Linear least square regression was performed on primary parasitoid Aphelinus abdominalis and is reported above, but this species was not included in the analysis of covariance reported in the text (see Supporting Methods). The df for each species is the number of data points minus 2. Summing the df column in the table yields 2,070, which, with 27 species in this table, corresponds to 2,070 + (27 ´ 2) = 2,124 data points. Data for 10 species of parasitoids (representing 27 data points) in the community reported in this study were not included in the regressions reported above due to fewer than 10 data points (see Supporting Methods). 2,124 (represented in the table above) + 27 (not represented in the table above) = 2,151, the total number of data points. The minimum and maximum lengths of all 2,151 aphids (including those omitted from the list above) were 0.69 and 3.97 mm, respectively.
