Abstract:By applying Dyar's ideas that the width of the head-capsule of a lepidopterous larva is more or less constant for any instar of a given species and that successive e larval instars of a given species show. a more or less regular geometric progression in the growth of the head-capsules, oriental peach-moth larvae are found to have four or five ins tars.
The number of larval instars produced is correlated with the rate of larval growth. As a rule rapid growth produces foun instars and slow growth five ins tars.
