Abstract
Regression equations are presented for the estimation of dry weight fr om head width and body length for 20 common New Zealand stream-dwellin g macroinvertebrate taxa. Equations for taxa grouped at order level ar e also provided. A power equation, y = a x(b) is used to express the r elationship between dry weight and body size. For the majority of taxa , dry weight could be estimated with more precision from body length t han from head width.
