What is it about?
Across animal species, ecology is associated with life span, body size and many other important traits. We show that metabolic rate is at the heart of these associations in insects, being affected by ecology and affecting many other traits. Our work places metabolic rate at the center of male and female reproduction and life histories.

Why is it important?
Ever since Darwin, we have known that ecology is linked with the evolution of many male and female traits. Our work provides an explanation of why these associations appear. More broadly, we show that it is necessary to measure metabolic rate in order to understand why traits evolve along different routes in different species and in the sexes.
