|Abstract: ||Caesalpinia crista L. is a straggling prickly shrub distributed throughout the hotter parts of India. Seeds are used as tonic, antiperiodic, antipyretic and in intermittent fevers. An outbreak of the common grass yellow butterfly, Eurema hecabe L. was observed during October – December, 2005 and 2006 on the shrubs at Indian Institute of Horticultural Research, Bangalore. Eggs were laid on lower surface of young leaves in groups of 70-90. Up to 800 eggs were found in clusters on one leaf. Eggs were white in colour measuring 1 mm x 0.5 mm in size, spindle shaped and glued to leaf. Soon after hatching (in 2-3 days), pale-green young larvae started feeding gregariously on lower surface of the leaves. Grown up larvae are long, green, rough, cylindrical or slightly depressed with a large head. Large number of the green coloured chrysalis pupae, were observed hanging from the twigs and gradually turned to brownish colour mimicking the colour of the surrounding dried plant parts. Adult butterflies are yellow in colour, observed to be hovering around the plant for mating and egg laying.|
