SummaryThe wandering spider Cupiennius salei Keys uses idiothetic orientation, i.e., memorized information about its own previous movements, to retrieve lost prey. Spiders, having been chased away from a prey fly, return to the capture site (the goal) over a distance of more than 75 cm even though all external orientation cues were precluded. This behavior and its sensory basis were examined by varying the proprioceptive and ‘motor command’ inputs to the memory and by ablating particular… Expand

Long-distance navigation in the wandering desert spider Leucorchestris arenicola: can the slope of the dune surface provide a compass cue?
3-D reconstructions of the paths revealed details about the processes involved in the spiders’ nocturnal way of navigation and suggest that gravity (slope of the dune surface) is an unlikely parameter used in path integration by the L. arenicola spiders. Expand
Use of local cues in the night-time navigation of the wandering desert spider Leucorchestris arenicola (Araneae, Sparassidae)
Results show that the burrows do not function as olfactory beacons for the homing spiders, as the comparatively small displacement distances could not be detected by means of global cues. Expand
A Neotropical armored harvestman (Arachnida, Opiliones) uses proprioception and vision for homing
It is found that vision is important for homing, and in the absence of visual cues, proprioception is important, and that the time of the day also influenced homing. Expand
Nocturnal Homing: Learning Walks in a Wandering Spider?
It is found that L. arenicola performs distinct stereotyped movement patterns during the first part of their departures in an unfamiliar area and that they seem to learn the appearance of their home during these movement patterns. Expand
Non-visual homing and the current status of navigation in scorpions
The results show that neither chemosensation nor vision, but rather path integration based on proprioception, plays a superior role in the homing of scorpions. Expand
Dead reckoning in a small mammal: the evaluation of distance
It is confirmed that mammals can derive the linear components of an outward journey from self-generated signals and therefore are able to judge the homing distance without relying on cues from the environment. Expand
Desert ants Cataglyphis fortis use self-induced optic flow to measure distances travelled
Even though optic flow cues are not the only ones used by the ants, the experiments show that ants are obviously able to exploit such cues for estimation of travel distance, indicating that the motion sensitive mechanism involved is different from mechanisms mediating the optomotor response. Expand

Arachnid navigation – a review of classic and emerging models
This work focuses on the most heavily studied spider models, highlighting the methodology used to deduce various aspects of the path integration machinery, and highlights some work being done on longer range spider navigators, and emerging work with other arachnid groups. Expand


Compound slit sense organs on the spider leg: Mechanoreceptors involved in kinesthetic orientation
Summary1.The hunting spiderCupiennius salei Keys is able to direct its locomotion by making use of information about its own previous movement sequences (kinesthetic orientation). After a blindedExpand
Slit sense organs and kinesthetic orientation
SummaryIn the hunting spider Cupiennius salei Keys, kinesthetic orientation towards a catching site from which it has previously been chased away is observed. This ability strongly depends on theExpand
Daily patterns of locomotor activity in a wandering spider
In DD, Cupiennius shows an endogenous activity rhythm with a mean period of 24.9 h (± 0.31, SE); typically during the first four to six cycles in DD the rhythm ‘splits’ into two components running at different frequencies, and in LL the walking activity became arrhythmic. Expand
Post-immobilization Wrapping of Prey by Lycosid Spiders of the Herbaceous Stratum
It is suggested that post-immobilization wrapping by wandering spiders serves the same general unction that it probably does in web-weavers--to prevent prey from dropping rom the spider’s elevated location down to the ground whenever it is released rom the chelicerae during (ceding, grooming, or subsequent capture attempts).

Ein atlas der spaltsinnesorgane von Cupiennius salei keys. Chelicerata (Araneae)
A survey was undertaken of all the slit sense organs to be found on the body of the spider Cupiennius salei, finding more than 3 000 sensory slits in the cuticle about half of which are combined to small groups of up to 29 slits forming compound or lyriform organs. Expand

The kinesthetic orienting mechanism is found to operate with striking precision within a certain area around the burrow and is able to control distance as well as direction (bi-coordinate or vector orientation). Expand
