SUMMARY The elevation of objects in the visual field has long been recognized as a potential distance cue, but it has been demonstrated to a reasonable extent in only four species: humans, frogs, fiddler crabs and backswimmers. Many tiger beetles hunt in flat, sandy areas, and their eyes show `flat-world' adaptations, such as an extended visual streak of higher acuity that corresponds to the horizon. They are therefore possible candidates for the use of elevation as a cue for distance. We… Expand
Tiger Beetle Biology and Visual Hunting Behavior
This review article covers the behavioral responses of the diurnal tiger beetle, including both the adults and larvae while hunting and adjusting to moving objects such as prey. This article providesExpand
Catch fast and kill quickly: do tiger beetles use the same strategies when hunting different types of prey?
Be Beetles are able to discriminate between different types of prey and apply different behavioural tactics to hunt it and it can be expected that such a type of hunting behaviour is characteristic also of other tiger beetle species. Expand
A tiger beetle's pursuit of prey depends on distance.
Evidence that tiger beetles adjust their control gain during their pursuit of prey is presented and it is found that the transition distance corresponds to the accuracy required to distinguish small prey from large predators. Expand
Visually targeted reaching in horse-head grasshoppers
Proscopids are capable not only of the sensorimotor transformations necessary for visually targeted reaching with their forelimbs but also of flexibly using different visual cues to target reaches. Expand
Static antennae act as locomotory guides that compensate for visual motion blur in a diurnal, keen-eyed predator
It is shown that a nocturnal tiger beetle species waves its antennae in elliptical patterns typical of poorly sighted insects, which enables timely detection of path obstructions followed by an increase in body pitch to avoid collision. Expand
A visual horizon affects steering responses during flight in fruit flies
During flight, fruit flies track visual features more strongly if they dip below a visual horizon, consistent with using the horizon to judge distance, which may help flies tune behaviors to nearby objects and features when they are too far off for motion parallax. Expand
A precocious adult visual center in the larva defines the unique optic lobe of the split-eyed whirligig beetle Dineutus sublineatus
The peculiar optic lobe organization of the larval and adult whirligig beetle Dineutus sublineatus is shown, for the first time, and it is shown that dual optic neuropils serve the upper aerial eyes and the lower subaquatic eyes. Expand
Hyperacute motion detection by the lateral eyes of jumping spiders
The contrast thresholds of male and female spiders are described, the reaction time between stimulus appearance and initiation of orientation, as well as the minimum distance a stimulus must travel before eliciting a saccade are investigated. Expand
Effects of knowledge of an endangered species on recreationists' attitudes and stated behaviors and the significance of management compliance for ohlone tiger beetle conservation.
Recreation is a leading cause of species decline on public lands, yet sometimes it can be used as a tool for conservation and management and education can mitigate the negative effect of recreation and promote conservation of endangered species. Expand
Decision‐making and motor control in predatory insects: a review of the praying mantis
Predatory and defensive behaviours require multiple stages of decision‐making in predatory insects, such as the praying mantis, as well as in non‐predatory animals such as flies. Expand


Fiddler Crabs Use the Visual Horizon to Distinguish Predators from Conspecifics: A Review of the Evidence
It has been concluded that crabs categorize stimuli as dangerous or otherwise by their position relative to the crabs’ visual horizon. Expand
Retinal location is the key to identifying predators in fiddler crabs (Uca pugilator).

It is concluded that a crab responds to stimuli according to their position relative to its retinal equator, which is discussed in light of the crabs' natural behavior with respect to supra-horizontal stimuli. Expand
Visual control of cursorial prey pursuit by tiger beetles (Cicindelidae)
  • C. Gilbert

  • Journal of Comparative Physiology A
  • 1997
When pursuing prey dummies, beetles track continuously and quickly follow changes in target position, suggesting closed-loop control using a position-sensitive servo mechanism, and limitations in signal detection, particularly spatio-temporal contrast, that may force beetles to use an open-loop system. Expand
The visual control of behaviour in fiddler crabs
It was found that males respond to moving objects of the right size as though they were conspecifics, although they do not resemble crabs in shape. Expand
Predator avoidance in fiddler crabs: 2. The visual cues
This work investigates the visual cues fiddler crabs Uca vomeris use to decide when to run towards their burrow in response to an approaching (dummy) predator by running towards theirburrow and proposes a two-tier antipredator response system and discusses the crabs' multistage response strategy in the context of the associated costs and the availability of information. Expand
Character Divergence and Convergence Among Tiger Beetles (Coleoptera: Cicindelidae)
Mandible length was found to be correlated with median prey size captured by tiger beetle species in Sulphur Springs Valley, Arizona, USA, and preliminary comparisons of sympatric tiger beetles from Canada and East Africa showed divergence but with a lower ratio. Expand
Visual mechanisms of hunting behaviour in Trite planiceps, a jumping spider (Araneae: Salticidae)
Two distinct post-detection hunting strategies are used; one enables spiders to catch their prey on the run, and the other controls the capture of stationary prey. Expand
Predator avoidance in fiddler crabs: 1. Escape decisions in relation to the risk of predation
This work explores the predator avoidance behaviour of the fiddler crab Uca vomeris by approaching crabs with small dummies intended to mimic a hunting tern and concludes that general models attempting to predict when animals should respond to an approaching predator need to incorporate the information that prey animals have available at the time of response.

Biology of Tiger Beetles
The goals of this article are to introduce tiger beetles to biologists seeking an ideal group of organisms for testing and integrating generalizations in such areas as ecology, physiology, behavior, morphology, phylogeny, and biogeography. Expand
Short communication: Substratum Slope and the Alignment of Acute Zones in Semi-Terrestrial Crabs (Ocypode Ceratophthalmus)
It is shown that, in principle, animals that live in a flat world could gain depth and size information from retinal position and retinal size alone and predicted that this alignment has to be under predominantly visual control and cannot involve the statocyst or leg proprioceptive inputs that are known to contribute to eye stabilisation in crabs.
