Head Capsule Widths as an Indicator of the Larval Instar of Codling Moth (Lepidoptera: Olethreutidae) [PDF]
Head capsule width was a reliable indicator of larval instar in a strain of Michigan codling moths, Cydia pomonella. Head capsules were 0.33, 0.50, 0.82, 1.18 and 1.55 mm in width from first to fifth instar respectively.
