Size Matters: Body Size is Correlated with Longevity in Speckled Cockroaches (Nauphoeta cineria).

Background: A relationship between body size and longevity has long been appreciated within eukaryotes, especially vertebrates.

Introduction: In general, the large size is associated with increased longevity among species of mammals and birds but is associated with decreased longevity within individual species such as dogs and mice. In this study, we examined the relationship between measures of individual body size and longevity in a captive population of speckled cockroaches (Nauphoeta cineria).
