(Lepidopera: Lycaenidae) was studied on field pea variety HFP 529 under laboratory conditions (26±1ºC; 60-70% RH). It was observed that 14 eggs/ female were laid singly on twigs, flowers and pods. Pre-oviposition, oviposition, postoviposition and incubation periods were from 1 to 2, 2 to 3, 2 to 3 and 2 to 3 days, respectively. Mean larval period was 2.5, 2.6, 3.3 and 3.6 days for 1st, 2nd, 3rd and 4th instars, respectively, with total larval duration of 12 days. Prepupal and pupal period was 2.22 and 8.00 days, respectively. The mean longevity of male and female was 8.0 and 9.5 days, respectively. Total life cycle varied from 29 to 35 days. Key words: Blue butterfly, Lampides boeticus, field pea,Pisum sativum, biology, longevity, oviposition, larval period, instars, pupal period Field pea, Pisum sativum is an important grain 70% RH). Sufficient numbers of larvae of L. boeticus legume crop in India cultivated in rabi season and in were collected from the field pea variety HFP 529 Haryana, it is grown in 15.56 thousand ha and production and reared in petri dishes lined with a blotting paper is 135.15 mt (Anonymous, 2018).
