Collected on sandal, Pterolobium indicum, Dodonea viscosa, Canthium didymum, lantana, Zizyphus oenoplia and Ageratum sp. (Chatterjee & Bose, 1933). Associated with aphids, mealybugs and scales infesting cabbage and other crucifers, brinjal, wheat, peas, tomato, Achyranthes aspera, Coccinea indica, Duranta repens, D. erecta, Zizyphus jujuba, chrysanthemum, neem, and several other plants (Afroze, 2000).

Seasonal occurrence

Chatterjee & Bose (1933) reported it as passing through many generations in a year (at least six), the populations being high during January-March, and August-December and low during April-July in South India (Chatterjee & Bose, 1933).
