A master of camouflage, the sandy tiger beetle, Cicindela limbata, is found in stabilized dunes and blowouts. Originally named from specimens collected in Nebraska in the nineteenth century, the sandy tiger beetle’s range barely extends into neighboring states. The wing covers are white, with some light markings of copper, green, or blue, which match the color of the sand. Although adapted to live on the hot sand, adults may hide in the shadows of plants or dig burrows to escape extreme temperatures. Adults are found from April until June and then again in late August into September. Eggs are laid in the spring, and the larva lives its entire life in a burrow, feeding on anything that comes near its entrance. Larvae probably spend two years in burrows, then they pupate in a side chamber and emerge in late August of the third year. Tiger beetles are predators and considered beneficial insects. Their large eyes allow them to detect small movements, and their short bursts of speed make them one of the fastest known insects. There are thirty-one species of tiger beetles in Nebraska, including the federally endangered Salt Creek tiger beetle.
