Blue butterfly

Biology and morphometrics of blue butterfly, Lampides boeticus infesting cowpea, was studied. The eggs were disc-shaped, finely sculptured and pale green in colour. The mean egg period observed was 3.20±0.20 days. There were four larval instars. The later instars were found attended by red ants in the field. The first instar caterpillar was fringed with hairs while second instar had sparse hairs. The third and fourth instar caterpillars were slug like, pea green in colour. The average sizes of the head capsule from first to fourth instars were found to be 0.11, 0.25, 0.63 and 1.
