Insect wings are living, flexible structures composed of tubular veins and thin wing
membrane. Wing veins can contain hemolymph (insect blood), tracheae, and nerves …

At rest, beetles fold and tuck their hindwings under the elytra. For flight, the hindwings are
deployed through a series of unfolding configurations that are passively driven by flap** …

Resilin is an elastomeric protein typically occurring in exoskeletons of arthropods. It is
composed of randomly orientated coiled polypeptide chains that are covalently cross-linked …

Birds, bats and many insects can tuck their wings against their bodies when at rest and
deploy them to power flight. Whereas birds and bats use well-developed pectoral and wing …

Ladybird beetles are high-mobility insects and explore broad areas by switching between
walking and flying. Their excellent wing transformation systems enabling this lifestyle are …

Traditional flap**-wing robots (FWRs) obtain lift and thrust by relying on the passive
deformation of their wings which cannot actively fold or deform. In contrast, flying creatures …

Insect wings consist almost entirely of lifeless cuticle; yet their veins host a complex
multimodal sensory apparatus and other tissues that require a continuous supply of water …

Micro air vehicles (MAVs) have wide application prospects in environmental monitoring,
disaster rescue and other civil fields because of their flexibility and maneuverability …

An insect's living systems—circulation, respiration, and a branching nervous system—
extend from the body into the wing. Wing hemolymph circulation is critical for hydrating …

Some Coleoptera (popularly referred to as beetles) can fly at a low Reynolds number with
their deployable hind wings, which directly enables a low body weight–a good bioinspiration …
