Research projects
The Exeter Bee Lab
We study the behaviour, senses and cognition of social insects, with a focus on bees, for understanding how sensory information is processed, memorised and used in the context of foraging activities, spatial orientation and navigation.
Much of our work investigates learning and how bees are guided by sensory information that is available in their natural environment, such as colours, pattern and odours of flower displays as well as less salient cues such as floral humidity or temperature patterns.
We ask how bees locate and choose individual flowers and flower patches or other places that are important to them, such as their nest. For example, tracking the elaborate movements and viewing patterns during learning flights in bumblebees, we can uncover how insects actively acquire sensory information that guides them towards their nest or flowers.
We are also interested how stressors, pathogens and pesticides, affect their cognitive capabilities, foraging and navigation.
Linking the mechanistic understanding of the insect brain, nervous system, senses and cognition to ultimate questions, we aim to provide novel insights about pollinator-driven selection in the evolution of floral signals and plant-pollinator interactions.
Methods range from behavioural experiments and observations in the field and in the lab to physiological studies. We also specialise in recording photometric spectral data to model how insects behave under different illuminations and perceive the colours of flowers and objects.
Our main model species are the European honeybee Apis mellifera and the Buff-tailed bumblebee Bombus terrestris. We collaborate with H Somanathan (IISER Thiruvananthapuram, India) contributing to the study of the behaviour and ecology of honeybees and stingless bees in the Asian tropics.
