Pawnee Montane Skipper

The Pawnee montane skipper habitat has been threatened by the proposed Two Forks dam and reservoir which would have inundated and destroyed 22% of the skipper’s habitat with an estimated loss of 23-42% of the population. Two large recent fires, Buffalo Creek Fire and Hayman Fire affected nearly half of the skipper habitat.

Poweshiek Skipperling

Poweshiek skipperling butterfly populations have shown a well-documented collapse in less than a decade between 2000 and 2010, with likely extirpation of over 95% of the populations. In 2000, Poweshiek skipperling was known from native prairie remnants in Iowa, Minnesota, North and South Dakota, and Wisconsin and in fens in Michigan. By 2010, it was no longer found in the Dakotas, Minnesota, and Iowa. The original core habitat range for the species was orders of magnitude larger than the current range. The cause of this wide-spread decline is still unknown.

Dakota skipper

Dakota skippers spend most of their life as larvae or caterpillars from approximately late July until the following June or July. After hatching, larvae form shelters of silk at the base of grass plants and construct larger shelters as they grow. Dakota skipper larvae overwinter either in these shelters or in buried shelters.

Prairie Mole Cricket

Male prairie mole crickets form aggressions or leks which are easy to locate from the loud call of the males. During the spring mating season, males call to flying females attracting them for mating from specialized acoustic burrows that are shaped like a bicycle horn and greatly amplify the sound of their calls. The male rubs its wings together after positioning itself with its head toward the back of the chamber, starting around sunset and ending at darkness.

American Burying Beetle

The minimum carrion size for breeding purposes is small birds or mammals. Beetles will fight over highly desirable carcasses until one dominant male and female American burying beetle remain. Together they bury the carcass using secretions to preserve it.
