Pat Willmer

Patricia 'Pat' Gillian Willmer is an entomologist and ecologist in the UK. She is emeritus professor of zoology at the University of St Andrews and is an expert in pollination.

Career and research
Willmer was initially a neurobiologist at the University of Cambridge, before moving into invertebrate physiology and eventually insect plant interactions.

She has researched pollination biology for over 30 years and she supports agricultural environmental schemes such as wildflower strips to support pollinating insects and enhance crop pollination.

Some of her interesting findings include flowers can change colour such as the legume Desmodium setigerum which changes from lilac to white to turquoise after being visited by a pollinating bee; and acacia plants that manipulate the ants that defend them, releasing a compound mimicking the ant alarm pheromone when they flower so that pollinating insects such as bees can visit.
