They are seen in large numbers with the panicle emergence and hibernate during winter in adult stage. It shows incomplete metamorphosis and there is no pupal stage in its life cycle. Copulation continued for 18 to 20 minutes and oviposition take place in the tissues of flowering shoots for 4 to 5 days. Eggs are smooth, creamy, oblong in shape and laid singly. Immature stages include five nymphal instars and the total nymphal period varies from 12 to 17 days. Adult male and female are creamish grey in colour and female (4.00-4.30 mm in length) is comparatively larger than male (3.80-4.20mm).Total life span of this species under laboratory conditions ranges from 18 to 22 days.
