Caption

SEM images of the microstructure of the adhesive hairs ('setae'). (A) Side view showing the up to 1.8 mm long hair shaft (not shown in full length) and the tip region covered with 'microtrichia' (minute hair-like structures on the hairs proper). (B) Top view of the 'scopula pad' (a dense tuft of hairs) on the lower side of the pretarsus. Covering the tip region of the hairs are spatula-shaped microtrichia, which stick to the substrate during walking. (C) Higher magnification image of the spatula-shaped microtrichia.
