This chapter outlines what is known about path integration in insects. It begins by discussing how the insect's compass and odometer work as well as the manner in which their outputs are combined. It then returns to the path integration system in general and explores how central place foragers such as bees and ants make use of the results of the path integration process. It is evident that the path integration system offers vectors that guide the animal to nesting and feeding sites or from one waypoint to another, and empowers the animal with a framework for obtaining and using spatial knowledge about its environment. In solving these navigational problems in an ad hoc rather than ab initio way, the insect attains high-level tasks by context-dependent low-level means. It is also shown that insects use a variety of information sources, such as the direction of the sun or the polarization patterns and spectral gradients in the sky, to determine their heading.

Keywords:   path integration, insects, path integration system, compass, odometer, polarization patterns, spectral gradients, spatial knowledge, navigation
