Symbiotic relationship between gecko and insect in Madagascar
BBC News highlighted an interesting relationship between a day gecko and a plant hopper insect in Madagascar. Apparently the lizard signals for food which is provided by the insect.
The lizard repeatedly nods its head at the insect, called a plant hopper, until it flicks over small balls of honeydew for the gecko to dine upon.
BBC says that in return, the lizard may offer some form of protection for the plant hopper.
