Behavioral ecologists have long studied the role of coloration as a defense against natural
enemies. Recent reviews of defensive coloration have emphasized that these visual signals …

Conversion of forewings into hardened covers, elytra, was a ground-breaking morphological
adaptation that has contributed to the extraordinary evolutionary success of beetles …

Many insects benefit from bacterial symbionts that provide essential nutrients and thereby
extend the hosts' adaptive potential and their ability to cope with challenging environments …

The cuticle exoskeleton plays a key role in facilitating the evolutionary success of insects.
Since the mid of the last century, many different biomechanical properties of exoskeletons …

Biological tissues may exhibit graded heterogeneities in structure and mechanical
properties that are crucial to their function. One biological structure that shows variation in …

Conglobation is an adaptive behaviour occurring independently in various animal groups.
Here, we study the evolution of conglobation in Ceratocanthinae, a beetle group with the …

Beetle's elytra provide elaborate microstructural designs to achieve functional synergies in
face of external environments. Natural design strategies can provide effective solutions to …

A striking characteristic of insect cuticle is the wide range of its material property values, with
respect to stiffness, strength and toughness. The elastic modulus of cuticle, for instance …

The brilliant appearance of Easter Egg weevils, genus Pachyrhynchus (Coleoptera,
Curculionidae), originates from complex dielectric nanostructures within their elytral scales …

The cuticle plays an important role in the evolutionary success of insects. Many studies on
insect cuticles have reported a soft, resilin-rich endocuticle. However, a recent study …
