Declines in survival and performance with advancing age (senescence) have been widely documented natural populations, but whether patterns of senescence across traits reflect a common underlying process biological ageing remains unclear. Senescence is typically characterized via assessments the rate change mortality (actuarial senescence) or phenotypic (phenotypic senescence). Although both phenomena are considered indicative declines somatic integrity, actuarial rates actually correlated has yet to be established. Here we present evidence from decade-long longitudinal field study wild insects. By tagging every individual using continuous video monitoring network up 140 cameras, were able record behavioral data on an entire adult population crickets. This reveals that vary substantially 10 annual generations. variation allows us identify strong correlation between measures senescence. Our demonstrates age-related reflected level observations single year may not representative general pattern.
