Developmental stages of a common grass yellow butterfly, eurema hecabe

Abstract

Developmental stages of pierid butterfly (Lepidoptera: Pieridae) Eurema
hecabe, duration and survival rate of developmental stages was studied in
laboratory condition under 29 ± 3ºC temperature with RH 78 ± 2%. Egg, five
larval instars and pupal stage were distinct. The average duration from egg to
adult, incubation period, larval and pupal period was recorded 22.0 ± 0.7, 5.7 ± 6,
10.5 ± 0.4 and 6.5 ± 0.4 days, respectively. Twenty seven out of 34 larvae were
successfully completed their whole 5 instars. Positive correlation among the
larval instars, amount of food consumption and excretion of faeces were
observed. About 65% pupae emerged as adult at laboratory condition.
