Abstract
The numbers of larval instars of Agrotis ipsilon (Hufnagel) were determined using measurements of larval head-capsule width. The obtained results emphasized that the head capsule width recorded was 0.28 mm for the 1st instar (newly hatched larvae) and 3.42 mm for the 6th instar (taken to pupation). The overall results fit in with Dyar s rule.
