Research output: Book/Report/Conference proceedingTechnical report


We conducted a baseline inventory of terrestrial Heteroptera (true bugs) and Orthoptera (grasshoppers, crickets and katydids) at foursites in Monroe and Randolph counties,Illinois in 2014, namely: Mill Creek Natural Area (MCNA); White Rock Nature Preserve (WRNP); Fogelpole Cave Nature Preserve (FCNP); and Kidd Lake State Natural Area (KLSNA).A total of 95 species in the focal taxa were recorded (67 Heteropteraand28 Orthoptera). In addition, a further 96 species of arthropods in groups other than Heteroptera and Orthoptera were also recorded.Heteropteran diversity was found to be typical of that expected for other natural areas in Illinois, though orthopteran diversity was much lower and may be related to structural aspects of the respective habitats.Cluster analysis of our presence/absence data revealed marked differences in site similarity between orthopteran and heteropteran species assemblages.
