Just like humans, crickets get old. Though we didn’t find evidence of ‘live fast, die young’ in this species, those that put more energy into reproduction early in life showed some signs of faster decline as they aged.

Insects are used to study aging in laboratories, but few studies have examined whether wild insects such as field crickets – whose adult life lasts a few weeks – experience aging in the sense of physical decline.

Researchers - Network - Video - Cameras - Hour

The researchers used a network of more than 130 video cameras to study every hour of the lives of a population of wild crickets in a Spanish meadow. They monitored reproductive effort, aging and survival over a ten-year period. They found that crickets that invested more in reproduction showed more signs of aging – chirping less and losing more fights.
