Navigating home is a very important task, often necessary for an individual's survival. For insects such as bumblebees, which frequently travel between their nest and foraging sites, this task is an impressive achievement, given the small size of their brains, the immense distances they travel and the nature of their nest entrances, which are often imperceptible to an inexperienced observer.  Surprisingly despite the large body of research regarding bumblebee navigation, there is no consensus on what strategies bumblebees use to return to their nests. It is hypothesized that, due to bumblebee near-panoramic vision, they likely use visual information that is readily accessible to them. However, this information is very dense and complex e.g.; Bumblebees can perceive colours, shapes, UV and even the relative distance to objects. Due to this complexity, the study of insect navigation requires the development of simple yet effective visually based navigation strategies. In this talk, I will present hypotheses present in the literature on how this visual information could be used for homing in bumblebees. Using a series of experiments designed to test how various vision-based strategies impact the return behaviour of bees in a visual conflict situation, I found that the relative distance to objects extracted from the response to contrast and apparent motion could improve return performance. I then describe how this information is gathered by the insect during its first flights out of the nest and discuss the possible role of odour footprints at the nest entrance in aiding visual guidance.
