Colour Selection and Olfactory Responses of Papilio demoleus during Foraging and Courtship.

ABSTRACT: Colours and odours are the most important cues for butterflies to localise food and mating partners. We studied the visual and olfactory responses of the widely distributed butterfly Papilio demoleus Linnaeus during foraging and courtship. P. demoleus visited odourless flowers with six colours except green and black, with red as the favourite colour (650-780 nm). Males and females differed in behaviour while visiting flowers. Males were more active than females during foraging. The application of honey water resulted in a significant increase in flower visits by both females and males, and they scarcely visited the apetalous branches with odours. Under natural conditions, four patterns were observed: males chasing males (42.28%), males chasing females (30.56%), females chasin
