Magnetic compasses in insects
Using magnetic information for orientation and navigation is widespread in animals. Insects use magnetic information for simple body alignment, homing or during long-distance migrations. Most often, insects use a polarity ...

Migration, Orientation and Navigation: Magnetic Compasses in Insects
The use of magnetic information for orientation and navigation is a widespread phenomenon in animals. In contrast to our knowledge of navigational systems in vertebrates, our understanding of the mechanisms underlying the ...
Do leafcutter ants, Atta colombica, orient their path-integrated home vector with a magnetic compass?
Leafcutter ants, Atta colombica, forage over 250 m in structurally complex, Neotropical rainforests that occlude sun or polarized light cues. Night foraging makes the use of celestial cues and landmarks all the more ...
Do leaf-cutter ants Atta colombica obtain their magnetic sensors from soil?
How animals sense, process, and use magnetic information remains elusive. In insects, magnetic particles are candidates for a magnetic sensor. Recent studies suggest that the ant Pachycondyla marginata incorporates ...
