Blue structural colors, produced by diverse tissue nanostructures, are known from all major vertebrate clades except cartilaginous fishes (e.g. sharks, rays). We describe a bright angle-independent structural blue from ribbontail stingray skin, arising from a novel cell type with unique quasi-ordered arrays of nano-vesicles enclosing guanine nanopl...

Synopsis From large ventral pleats of humpback whales to nanoscale ridges on flower petals, wrinkled structures are omnipresent, multifunctional, and found at hugely diverse scales. Depending on the particulars of the biological system—its environment, morphology, and mechanical properties—wrinkles may control adhesion, friction, wetting, or drag;...

The plant cuticle is a multifunctional barrier that separates the organs of the plant from the surrounding environment. Cuticular ridges are microscale wrinkle-like cuticular protrusions that occur on many flower and leaf surfaces. These microscopic ridges can help against pest insects by reducing the frictional forces experienced when they walk on...

Cuticular ridges on plant surfaces can control insect adhesion and wetting behaviour and might also offer stability to underlying cells during growth. The growth of the plant cuticle and its underlying cells possibly results in changes in the morphology of cuticular ridges and may also affect their function. We present spatial and temporal patterns...

Controlling the interaction of insect populations with their host plants has recently received renewed attention in the light of pest control. One way to modify the interaction of insects with their host plants in a non‐chemical way is through influence of their de/attachment. Insect detachment has been observed for textured biological and structur...

Cuticular ridges on plant surfaces can control insect adhesion, wetting behaviour and might also offer stability to underlying cells during growth. Yet, the influence of ontogenetic changes in the morphology of such surface microstructures on interactions of insects with plant organs has been largely neglected. In this study, we present spatial and...

The surfaces of animals, plants and abiotic structures are not only important for organismal survival, but they have also inspired countless biomimetic and industrial applications. Additionally, the surfaces of animals and plants exhibit an unprecedented level of diversity, and animals often move on the surface of plants. Replicating these surfaces...
