Investigating the nanomechanical properties and reversible color change properties of the beetle Dynastes tityus

Investigation of the selective color-changing mechanism of Dynastes tityus beetle (Coleoptera: Scarabaeidae)

“…In the middle of pit, fractural like pillar was found. Figure 1 g gives the photonic nanoarchitectures under epicuticle (EPI) of elytron interior 23 . Figure 1 h shows a middle SEM image from the FIB milling process, which clearly reveals two different layers in the inner structure.…”

Bio-inspirations for the Development of Light Materials based on the Nanomechanical Properties and Microstructures of Beetle Dynastes tityus

“…The material in this layer is photonic crystals with porous microstructure. With this special microstructure, the elytra of D. tityus can change its color, for example from deep brown at a relative humidity of 98% to yellow green at a relative humidity of 34% as shown in Fig. 1a [21] .…”
