White-eyes Zosterops japonica sucked Honey-dews secreted by Jumping Plant-lices (Homoptera, Psylloidea)

Abstract

We observed that Japanese White-eyes Zosterops japonica sucked honey dews secreted by two species of small jumping plant-lices, Heterophylla cubana and Stenopsylla nigricornis. This is the first observation of inter-specific relationship between homopteran insects and white-eyes. Such a foraging manner might be common in White-eyes. Although honey dew of homopteran insects is not neccessary to White-eyes as nectar resource, the homopteran insects seems important as insect foods.
