Results of the canonical discriminant function analysis for Drosophila mojavensis cuticular hydrocarbons for the first two canonical variates. Differences due to temperature were statistically significant in agria‐reared flies (Wilk's λ = 0.138, F = 4.31, df = 62/158, p < .0001) and organ pipe‐reared flies (Wilk's λ = 0.222, F = 2.86, df = 62/158, p < .0001). The six cactus–temperature class means are plotted showing that much of the variation in CV2 was due to organ pipe‐reared adults exposed to 35°C. The two plotted lines are the regressions for agria vs. organ pipe‐reared adults
