Comparing color learning and brain morphology across bumblebee queens, gynes, and workers
Comparing color learning and brain morphology across bumblebee queens, gynes, and workers
Recent work has shown that young bumblebee queens are better at learning color associations than workers, so in this study we look at the brain morphology of bumblebee queens, gynes, and workers to understand how these behavioral differences may be reflected in the brain and if there are changes to queens as they transition from solitary foragers to reproductives that live in the dark.

Are bumblebees primed to learn ecologically-relevant color-scent combinations?
Are bumblebees primed to learn ecologically-relevant color-scent combinations?
In a multi-modal absolute conditioning paradigm we tested if scents that tend to co-occur with certain colors were easier for bumblebees to learn than if scents were not present or when they were paired with a color they did not tend to co-occur with. Analyses are ongoing, but currently do not find evidence that co-occurring color scent combinations are easier to learn.
