Orthoptera species diversity and composition at Wilderness State Park.

Abstract

As anthropgenic influences continue to effect our environment, the conservation of biological diversity is becoming increasingly important. Species preservation is vital to the healthy functioning of our planet and begins with biodiversity surveys. Our survey, conducted at Wilderness State Park in Emmet County, MI, surveyed the species composition of four different groups of insects: Lepidoptera (Butterflies only), Coleoptera (Cerambycidae only), Odonata, and Orthoptera. This paper focuses on order Orthoptera (Grasshoppers, Crickets, and Katydids) in particular. To carry out our biodiversity assessment, sampling occurred in various habitats within the park, chosen to best represent the park’s overall habitat diversity. Various collection methods were used to collect the highest number of species and individuals possible. Several species of Orthoptera were collected within the park, including the state-threatened Trimerotropis huroniana (Lake Huron Locust), and six species previously not on record in Emmet County. Our results gave a clearer understanding of what habitats are healthy within Wilderness State Park, and what steps may be taken by park management to continue successful preservation.
