Study was carried out on the biology and population dynamics of Common banded awl Hasora chromus Cramer in Pongamia pinnata under normal temperature of 27+2 ^oC and photoperiod conditions (day: night 12:12 hrs). In the Post Graduate Laboratory of College of Forestry, OUAT, Bhubaneswar. Results revealed that egg period was 1.58±0.45 days. There were five larval instars and it took 16.25±0.45 days to enter into the pupal stage. Pupation took place inside the webbed leaves and pupal period was lasted for about 5.85 and 6.65 days respectively. Adult longevity of male and female moths were 5.25 and 5.65 days respectively. The pre ovipositional, oviposition and post-oviposition periods were found as 3.00, 4.25 and 1.50 days respectively. The duration of total life cycle of adult male and female was 24.25 and 25.50 days respectively. Nutritional indices like growth rate (GR), consumption index (CI) and approximate digestibility (AD) decreased along with the growth of larvae. Efficiency of conversion of digested food (ECD) and efficiency of conversion of ingested food (ECI) were decreased.
