Rhopaloceran butterflies are well known to visit distinct species of flowers in order to extract nectar, normally leaving again after a short time to continue their foraging flights. Females of Agapetes galathea , however, often show a different behaviour, which is the subject of the following analysis. The dynamics of sugar production by flowers and the foraging pattern of the galathea‐ ♂♂ have been studied under natural conditions. Special consideration is given to the aggressive behaviour of the females towards approaching insects during their flower resting periods.
