| Use of local cues in the night-time navigation of the wandering
desert spider Leucorchestris arenicola (Araneae, Sparassidae) |
|
|
Abstract:
Adult male Leucorchestris arenicola can
walk round-trips of several tens of meters in search of
females. Most excursions end with the spiders returning
to their burrow. For small animals homing over distances
of several meters is theoretically impossible
without the aid of external cues. It was investigated,
whether the spiders use local cues or they rely solely on
global cues. Individually marked male spiders were
captured during their excursions and displaced several
meters inside an opaque box. Ten out of twelve displaced
spiders returned to their burrows. This shows
that the male L. arenicola are using local cues during
their homing, as the comparatively small displacement
distances could not be detected by means of global, e.g.
celestial cues. In order to test whether the spiders
could be using olfactory guidance, the burrows were
displaced by 2 m while the spiders were out on their
journeys. In 12 out of 15 experiments, the spiders did
not Wnd their burrows. These results show that the burrows
do not function as olfactory beacons for the homing
spiders. |
