Information design for insects

The Long-Proboscid Fly of South Africa uses the arrow-shaped markings on these native iris flowers to guide their tongues into the centre to extract nectar. In the process they pick up pollen which they transfer from flower to flower as they feed. Biologist, Dennis Hansen, from the University of Kwazulu-Natal, found that when the markings were painted out the flies failed to locate the nectar and, consequently, were unable to pick up any pollen.
