From: Can snow depth be used to predict the distribution of the high Arctic aphid Acyrthosiphon svalbardicum (Hemiptera: Aphididae) on Spitsbergen?

Figure 6

Range of snow depth measured at each phenological stage on occupied and unoccupied patches. The box plot shows snow depth measured in April for those patches where aphid presence (P) or absence (A) was recorded the following August, grouped by phenological stages (0: No bud visible; 1: Stamens visible; 2: Petals senescing; 3: Seed head visible above petals; 4: Seed head untwisting; 5: Seed head twisting), with standard deviation (solid bars) and outliers (dots).
