When a butterfly emerges from its chrysalis, one of the first things it must do is assemble its mouthparts. Butterflies, and most nectar-feeding insects, use a long tube called a proboscis to feed.

Researchers observed that the coiling action of the butterfly proboscis, a tube-like 'mouth' that many butterflies and moths use to feed on fluids, resembled a spiral similar to that of the Golden ...

The feeding apparatus of butterflies and moths has drawn considerable attention owing to its specialised morphology and its critical role in ecological interactions. The proboscis is a highly derived, ...

(Nanowerk News) New discoveries about how butterflies feed could help engineers develop tiny probes that siphon liquid out of single cells for a wide range of medical tests and treatments, according ...

Alongside Leonardo Da Vinci's Vitruvian Man, disc-shaped galaxies, or the cochlea of the human ear, scientists can now count sap-feeding butterfly proboscises as aligned with the Golden Ratio. The ...
