Tiger beetles of Missouri: distribution, habitat preferences, seasonal occurrence, andcomments on species of conservation concern.
Ted C. MacRae and Christopher R. Brown have been conducting informal surveys of tiger beetles (Coleoptera: Carabidae: Cicindelinae) across Missouri since 2000. To date, 24 species in seven genera have been documented occurring within the state, all but one of which are considered permanent residents. Geographical affinities include 4 species (17%) with transcontinental distributions, 10 species (42%) occurring broadly east of the Rocky Mountains, 8 species largely restricted to the Great Plains and surrounding areas (33%), and 2 species (8%) occurring across the southern U.S. Preferred habitats include riparian corridors, upland forests, wet bottomland forests, prairies (including xeric dolomite/sandstone glades, relict sand prairies, and loess hilltop prairies), saline springs, and agricultural lands. Five species of potential conservation concern were identified due to their highly restricted occurrence in the state combined and specialized habitat requirements and are discussed in detail.
