Changes in structural and pigmentary colours in response to cold stress in Polyommatus icarus butterflies

Abstract While numerous papers have investigated the effects of thermal stress on the pigmentary colours of butterfly wings, such studies regarding structural colours are mostly lacking, despite the important role they play in sexual communication. To gain insight into the possible differences betwe...
