a–c Schematics of springtail cuticles (Collembola) with mushroom-shaped overhanging features that enable them to entrap air upon water immersion. Artistic reconstruction of cuticles and its cross-sectional view along the dotted lines in Fig. 1b inspired by Supplementary Fig. 1 and images presented previously28. d–f Representative SEM image of the top view, cross-sectional view along the dotted lines in Fig. 1d, and magnified view of DRCs with diameter D = 200 µm and depth h ≈ 67 µm.
