Category:Signaling (pollination)

Note: In this category “signaling” (also spelled “signalling”) refers to the phenomenon when flowers that are maintained in fresh condition beyond the end of their sexual viability, undergo dramatic, often localized colour changes. Pollinators recognize the colour change as a signal, and concentrate their visits on rewarding and sexually viable pre-change flowers. As a result both participants benefit from the interaction in that the plants receive efficient pollination service, and the insects are more productive in being accurately directed to rewarding flowers. Each image must display at least TWO colour forms.
