Relationship between body mass (ln g) and body size (ln mm) as described by ordinary least squares (OLS) regression in Gryllus texensis for (A) each sex separately (males: triangles and dashed line; females: circles and dotted line) and (B) for each level of diet quality (poor diet: triangles and dashed line; good diet: circles and dotted line) for the Kelly and Tawes (2013) data. The common OLS slope is represented by the solid line in both plots.
