Bruneau Dunes Tiger Beetle
A high-speed predator found only around Bruneau’s dunes hunts across open sand while its larvae ambush prey from tiny vertical burrows.
Artwork inspired by Robert Limbert
Tiger beetles run, stop, and run again because speed can briefly exceed their ability to process visual information. Adults use large jaws to seize small prey; larvae anchor inside sand burrows with hooks and strike upward. Close-focus binoculars can reveal shape and pattern without a pursuit across fragile ground.
Stay on established routes and open recreation zones, never dig at larval burrows, and do not collect. Dune margins that look empty may contain larvae or eggs. Photograph from a low distance only when doing so does not crush vegetation or widen informal paths.

Good to know
A close image of Bruneau Dunes Tiger Beetle is not automatically decisive: habitat, timing, full structure, and the alternative species considered should remain part of the record.
Notice these
- A fast ground beetle with long legs, large jaws, metallic bronze-green tones, and pale markings on the wing covers
- Open sand and dune margins in the Bruneau Dunes system of southwestern Idaho
- Runs rapidly over open sand and flies short distances when approached; larvae wait in vertical burrows to seize passing prey.
