The number of larval instars is important from both theoretical and practical perspectives.
Three previous studies based on head capsule widths (HCWs) have suggested that …

For herbivorous insects with a broad diet breadth, host plant identity can influence larval
development by either accelerating or delaying growth. For some species of Lepidoptera …

Various insect species display a uniform geometric increase in size during the larval stage
(that is they follow the Brooks‐Dyar rule). Here, results of larval development are presented …

Abstract The mean width (n= 5) of the cephalic capsule instar of Lymantria obfuscata (Indian
Gypsy Moth) was determined. During the course of investigation, average temperature and …
