Abstract
The application of Dyar's Law to lepidopterous larvae has been discussed by numerous investigators, who have shown that in many species the head-widths follow a regular geometrical progression in successive instars. Taylor reviews Dyar's Law thoroughly and tests it out on the sawfly, Phyllotoma nemorata (Fallen). The same author examines Dyar's measurements on 46 species of sawfly larvae and concludes that Dyar's Law holds as well for the sawfly larvae as for the 28 species of lepidopterous larvae on which the rule was originally based.Keywords
