NUS discovery: Butterflies can acquire new scent preferences and pass these on to their offspring
Two studies from the National University of Singapore demonstrate that insects can learn from their previous experiences and adjust their future behaviour for survival and reproduction.
Beating the Heat in the Living Wings of Butterflies
Columbia engineers and Harvard biologists discover that butterflies have specialized behaviors and wing scales to protect the living parts of their wings. The nanostructures found in the wing scales could inspire the design of radiative-cooling materials to help manage excessive heat conditions; the sensory network in the wings could inspire the design of advanced flying machines.
Persistence pays off with first images of butterfly eggs
Kim Moss, assistant professor of art and visual culture and coordinator of the biological and premedical illustration program at Iowa State University, is the first person to shoot video and photos of where the Parnassius clodius butterfly lays its eggs — a missing piece of the puzzle that helps explain its link to climate change.
Monarch butterfly parasite uses strategy to spread infection
Harmful parasite of monarch butterflies uses multiple transmission strategies to keep infection levels high
Monarch butterflies bred in captivity may lose the ability to migrate, study finds
Commercially-bred monarchs are genetically distinct from wild counterparts and do not fly southward, even in offspring raised in natural, outdoor conditions. Monarch butterflies purchased from a commercial breeder did not fly in a southward direction, even in offspring raised outdoors,…
