Figure 1: Corolla and proboscis lengths of seven Nicotiana species and the potential pollinator Manduca sexta.

From: Innate olfactory preferences for flowers matching proboscis length ensure optimal energy gain in a hawkmoth

Figure 1

Grey boxes indicate corolla lengths that significantly differ from the length of the moth proboscis (orange box, dotted line indicates proboscis median length; P<0.05, Kruskal–Wallis test followed by Holm corrected Wilcoxon rank-sum test), while the length of the N. alata corolla (white box) does not differ from the proboscis length (P>0.05). Bar plots next to the flower names indicate absolute differences between corolla length and the moth’s proboscis (cm).
