The Salt Creek tiger beetle, Cicindela nevadica lincolniana, is a critically endangered subspecies of tiger beetle endemic to the saline wetlands of northern Lancaster County, Nebraska, adjacent to and immediately to the north of the city of Lincoln. It is a predatory insect, using its mandibles to catch other insects. The beetle is one of the rarest insects in North America; as of 2005, the total population is believed to be about 150 individuals.

Physical description

The Salt Creek tiger beetle measures about 12 mm (0.5 in.) in length. The beetle has a metallic brown to dark olive green coloration, with a dark metallic green underside. Its body form and color pattern differs from other tiger beetle subspecies.


Life cycle

Little is known about the life cycle of the Salt Creek tiger beetle. Adults emerge around June 1 and disappear five or six weeks later; populations peak about two weeks after the beetles' initial emergence. After mating, the beetles lay eggs in sloping, muddy, saline soil.


Upon hatching, the larva constructs a burrow. The larva is a voracious feeder, capturing prey that wanders too close to the burrow. During the larval stage, the beetle will molt multiple times (the precise number is unknown, but most other tiger beetles have three larval stages). If a three-stage cycle does exist, it is likely that the Salt Creek tiger beetle spends over a year in the third larval stage. A larva (Latin; plural larvae) is a juvenile form of animal with indirect development, undergoing metamorphosis (for example, insects or amphibians). ...


The larva prepares for its pupation by digging a side chamber and sealing the burrow entrance. Chrysalis of Gulf Fritillary in Georgetown, South Carolina Pupation of Aglais urticae A pupa (plural: pupae or pupas) is the life stage of some insects undergoing transformation. ...


Habitat

The beetle is found along the banks of Salt Creek and its tributaries and in the mud flats of saline marshes of northern Lancaster County. Its historical range is believed to have included similar habitat in extreme southern Saunders County. Much of this habitat has been degraded or destroyed by drainage of the salt marshes for agriculture or development and by runoff from surrounding farms and the city of Lincoln. In geography, a marsh is a type of wetland, featuring grasses, rushes, reeds, typhas, sedges, and other herbaceous plants (possibly with low-growing woody plants) in a context of shallow water. ...

Conservation

Interest in the Salt Creek tiger beetle began with surveys conducted by the University of Nebraska-Lincoln in the mid-1980s. These surveys indicated that the beetle was quite rare; an in-depth study of the beetle began in 1991. The beetle was added to the Nebraska endangered species lists in the 1990s. On October 6, 2005, the U.S. Fish and Wildlife Service listed the beetle as an endangered species under the federal Endangered Species Act.

From 1991 to 2005, the number of sites containing Salt Creek tiger beetles has declined from six to three.
