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 1 instar (newly hatched larvae) and 3.42 mm for the 6 instar (taken to pupation). The overall results fit in with Dyar's rule. © 2011 Jordan Journal of Biological Sciences. All rights reserved
