Dynamic visual cues induce jaw opening and closing by tiger beetles during pursuit of prey

  journal={Biology Letters},
In dynamic locomotory contexts, visual cues often trigger adaptive behaviour by the viewer, yet studies investigating how animals determine impending collisions typically employ either stationary viewers or objects. Here, we describe a dynamic situation of visually guided prey pursuit in which both impending prey contact and escape elicit observable adaptive behaviours in the pursuer, a predatory beetle. We investigated which visual cues may independently control opening and closing of the… 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
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
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
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
Expansion rate based collision avoidance for Unmanned Aerial Vehicles
A vision based collision avoidance approach for UAVs, based on potential field method, designed over the UAV's heading using the relative heading to the goal and to obstacles, the distance to thegoal, and the expansion rate of obstacles is proposed. 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
Tiger beetles pursue prey using a proportional control law with a delay of one half-stride
A physical interpretation of the observed control law is proposed: to turn towards its prey, the beetle on average exerts a sideways force proportional to the angular position of the prey measured a half-stride earlier. 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 visually evoked escape response of the housefly
An examination of several visual parameters reveals that the darkening contrast, measured from the onset of stimulation to the start of escape is nearly constant for a variety of stimuli that trigger escape reliably, and may be crucial in eliciting the visually evoked escape response. Expand
Visually mediated snapping in the bulldog ant: A perceptual ambiguity between size and distance
  • S. Via
  • Biology
  • Journal of comparative physiology

These experiments with the isolated head preparation show that the bulldog ant cannot judge the absolute distance of a target in the visual field when limited to primary visual cues, and suggest that two eyes are better than one simply because they provide more input. Expand
How hoverflies compute interception courses
Summary1.Males of many species of hoverfly hover in one spot ready to pursue passing objects, presumably in order to catch a mate. We have filmed two of the larger species as they begin their pursuitExpand
Relation between aiming and catch success in larval fishes
A model comparing the ratio mouth radius/aiming inaccuracy to catch success of stationary prey accurately predicted catch success for larval carp feeding on Artemia nauplii and for larva pike feeding on Daphnia, and seemed unimportant in determining catch success. Expand
Invariance of Angular Threshold Computation in a Wide-Field Looming-Sensitive Neuron
The results indicate that LGMD is a reliable neuron with which to study the biophysical mechanisms underlying the generation of complex but invariant visual responses by dendritic integration and suggest that invariance arises in part from non-linear integration of excitatory inputs within the dendrite tree of the LGMD.

predatory behaviour of white sharks (carcharodon carcharias) at seal island, south africa
Analysis of white shark upper tooth morphology and spacing suggest the reversed intermediate teeth of white sharks occur at the strongest part of the jaw and produce the largest wound, which is the first evidence of social influence on predation in any elasmobranch. Expand
Chasing behaviour of houseflies (Fannia canicularis)
It is concluded that the control system actually used by the fly is accurately described by conclusions 2–4, and simulations predict correctly the manoeuvres and outcomes of quite complicated chases. Expand
