NUS study: A simple DNA switch helps tropical butterflies change wing patterns with the seasons
Singapore, 24 October 2025 — Scientists from the National University of Singapore (NUS) have discovered a simple DNA “switch” that helps tropical butterflies adjust the size of their wing eyespots in ...

Nanoscale cuticle mass density variations influenced by pigmentation in butterfly wing scales
Nature Communications - Here, the authors investigate the interaction of pigment distribution and cuticle density within butterfly wing scales. They use ptychographic X-ray computed tomography to...

For those interested in the evolution of phenotypic plasticity - Shen Tian et al. found that a novel bit of DNA - a Hox gene promoter in the genome of satyrid butterflies - boosts plasticity in the size of their eyespots in response to temperature.

A novel Hox gene promoter fuels the evolution of adaptive phenotypic plasticity
Adaptive phenotypic plasticity allows organisms to display distinct phenotypes in response to variable environments, but little is known about the genomic changes that promote the evolution of plastic...
