Tiger Beetle Biology and Visual Hunting Behavior

  title={Tiger Beetle Biology and Visual Hunting Behavior},
  author={Brandon Ewals-Strain bewalsstrain},
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 provides examples of binocular and monocular vision used by the predacious beetles, a type of distance control or measuring device. The larvae of the tiger beetle are ambush predators that sit in open sandy areas in burrows that it has built awaiting prey that comes within range. When prey approaches, the… Expand


Behavioural responses of the tiger beetle larva to moving objects: role of binocular and monocular vision.
It is concluded that visual information about hunting range in the tiger beetle larva is extracted both peripherally by the spatial pattern of image clarity and centrally by binocular vision. 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.

The role of target elevation in prey selection by tiger beetles (Carabidae: Cicindela spp.)
It is indicated that tiger beetles use elevation to estimate distance to prey, and that it is therefore one of the determinants of prey selection. Expand
Dynamic visual cues induce jaw opening and closing by tiger beetles during pursuit of prey
The ‘sloppiness' of such variation in the lag of the behavioural response, especially jaw closing, is discussed as an adaptation to uncertainty about target position due to degradation of the target image by motion blur from the fast-running beetle. Expand
Diurnal Tiger Beetles (Coleoptera: Cicindelidae) Capture Prey Without Sight
Results show that other modalities can be used by tiger beetles during prey capture, and suggest the need to test underlying assumptions of even well-studied organisms. Expand
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
Hidden burrow plugs and their function in the tiger beetle, Cosmodela batesi (Coleoptera, Cicindelidae)
The burrowing and plugging behavior of the tiger beetle, Cosmodela batesi (Fleutiaux), in the field and in the laboratory is documents, suggesting that it is likely an important adaptation of C. batei to its habitat. Expand
Diurnal Activity and Territorial Behavior of Pseudoxycheila tarsalis Bates (Carabidae: Cicindelinae)
Both sexes of P. tarsalis showed some fidelity to an area, but males ranged only about half as far as females, and males may derive a reproductive advantage by restricting their range and waiting for receptive females, even those ovipositing. Expand
Multitasking in an eye: the unusual organization of the Thermonectus marmoratus principal larval eyes allows for far and near vision and might aid in depth perception
The optical measurements are expanded and an unusual visual mechanism is outlined that is likely to be essential for the extraordinary hunting ability of these larvae. Expand
Unexpected Vegetarian Feeding Behaviour of a Predatory Tiger Beetle Calomera littoralis nemoralis (Olivier, 1790) (Coleoptera: Cicindelidae)
An unexpected vegetarian feeding behaviour in a predatory tiger beetle Calomera littoralis nemoralis was observed on the marine sandy beach in Albania during eating grains of maize and coocked macaroni, the first known case of feeding on plant grains by Cicindelidae species. Expand
