Research Abstract |
Most animal navigators use light compasses such as sun compassto perform their navigation. However, the light compass involves several problems that are related to instability. The present study has clarified that two factors, namely“distance to compass reference” and “disappearance by obstacle” influence to theinstability of the light compass in the provisioning navigation of subsocial burrower bugs. And the experimental results have shown that these species independently processes multiple compass references in a light compass to compensate for the instability problems.
