• compliance of the tip. Here, we mimic this feature using tilted, mushroom-like, stiff fibers comprised of a stiff stalk of elastic modulus 126 MPa, a softer tip of elastic modulus 8.89 MPa, and a joint-like element of elastic modulus 0.45 MPa (very soft), 8.89 MPa (soft), or 126 MPa (stiff) in between. The

• , termed as a joint-like element, is evidenced by the difference in color of this joint from the stalk or the tip (see Figure 1a). The joint-like element is believed to be more flexible and equips the fibers with the necessary articulation to better adapt to the target surface [32]. This joint can consist

• structures connecting claws and pulvilli to the terminal tarsomere [43][50]. In the pretarsus of the drone fly (Eristalis tenax) (Insecta, Diptera, Syrphidae), for example, membranous cuticle with large proportions of resilin forms a spring-like (or joint-like) element (Figure 3A–C) that makes the pulvilli
