Sensory ecology of feeding in the hummingbird hawkmoth Macroglossum stellatarum (Lepidoptera : Sphingidae)

摘要

The European hummingbird hawkmoth, Macroglossum stellatarum (Linnaeus 1758), drinks nectar while hovering in front of flowers of all colours, odours, sizes and shapes. Naive moths orient predominantly towards visual stimuli and prefer blue flowers with a radial pattern and a central contrasting spot. Hummingbird hawkmoths have trichromatic colour vision and can learn any colour and different patterns and sizes of flowers. Odour learning, however, depends on flower colour and docs, not take place when the colour is very attractive on its own.
