This characteristic imposes significant challenges in terms of

(B) High water contact angle on Collembola cuticle demonstrates natural super-hydrophobicity. (C,D) Multiscale structuring of the Collembola skin renders the

The Salvinia hair type appears to represent the result of evolutionary adaptation to a high performance and is, therefore, considered as an attractive biological model for applications requiring surfaces that remain dry upon immersion [5][29].

Previous studies have suggested that overhanging surface structures play an important role, but such structures are not a universal trait among springtails with superhydrophobic cuticles.
