Abstract

Chromolaena odorata is a seasonal weed and grows like a cultivated crop. It flowers during October-December. The floral characteristics such as white to purple colour of florets, short-tubed narrow corolla with deep seated nectar, the morning anthesis and the flat-topped head inflorescence providing a standing platform are important attractants for visitation by butterflies. The florets attract butterflies of five families and sphingid hawk moths. Among the butterflies, nymphalids are diverse and visit the florets consistently; their visits effect pollination. The diurnal hawk moths, Macroglossum gyrans and Cephonodes hylas also visit the florets during dawn and dusk hours for nectar, and effect pollination. Therefore, C. odorata, being an exotic is an important nectar source for adult butterflies.
