Amber-encased fossil shines light on evolution of bioluminescent insects
Trapped in amber for ~100 million years, an exceptionally well-preserved, light-producing beetle sheds light on the diversification of bioluminescent beetles in the Cretaceous period and provides the missing fossil link between fireflies’ living relatives.

Asian butterfly populations show different mimicry patterns thanks to genetic ‘switch’
A new study by researchers at the University of Chicago and the City College of New York (CCNY) has identified a unique, genetic “mimicry switch” that determines whether or not male and female Elymnias hypermnestra palmflies mimic the same or different species of butterflies.
