Instability and compensatory processing of a light compass in insects

大多数动物航海家使用日光罗盘等光罗盘进行导航。然而，光罗盘涉及到几个与不稳定性有关的问题。本研究澄清了两个因素，即“指南针参考距离”和“被障碍物消失”，这两个因素影响了亚社会洞穴昆虫补给导航中光指南针的不稳定。实验结果表明，这些物种独立地处理光指南针中的多个指南针参考，以补偿不稳定问题。

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.
