Western Tiger Beetle

Tiger beetles often have large bulging eyes, long, slender legs and large curved mandibles. All are predatory, both as adults and as larvae.
The larvae of tiger beetles live in cylindrical burrows as much as a meter deep. They are large-headed, hump-backed grubs and use their humpbacks to flip backwards, for the purpose of capturing prey insects that wander over the ground. The fast-moving adults run down their prey and are extremely fast on the wing, their reaction times being of the same order as that of common houseflies.
Tiger beetles are considered a good indicator species and have been used in ecological studies on biodiversity. Several species of wingless parasitic wasps in the genus Methocha (family Tiphiidae), lay their eggs on larvae of various Cicindela spp., such as Cicindela dorsalis.- Wikipedia.
