Fig. 7From: Leaves that walk and eggs that stick: comparative functional morphology and evolution of the adhesive system of leaf insect eggs (Phasmatodea: Phylliidae)Detachment forces on hydrophilic and hydrophobic substrates. A Phyllium letiranti, pinnate egg type with type 5 pinnae unevenly distributed on the egg capsule with tufts posteriorly. B Phyllium mabantai, pinnate egg type with type 5 pinnae evenly distributed laterally. C Phyllium rubrum, pinnate egg type with type 5 pinnae evenly distributed laterally. D Phyllium jacobsoni, pinnate egg type with type 5 pinnae evenly distributed laterally. E Cryptophyllium celebicum, mossy egg type with short type 1 pinnae. F Pulchriphyllium bioculatum, fused fins egg type with glue deposited on the wing-like fins. Colours indicate the surface chemistry of the substrate. The graphs show the median. Asterisks indicate statistical significance (* = p < 0.05, one-way repeated measures ANOVA followed by Holm-Šídák post hoc test, or Friedman’s repeated measures ANOVA on ranks followed by Tukey respectively; N = 15 for each measurement)Back to article page
