Length-Weight Relationships of Shrub-Steppe Invertebrates1

Abstract

The relationship between length and weight was investigated for common invertebrates inhabiting the shrub-steppe of south-central Washington. Three models were evaluated—a power function, an exponential function, and a linear function. The power function best describes adult and nymphal insects and Lepidoptera larvae. Coleoptera larvae were best described by a linear relationship, and Diptera larvae by an exponential function.
