Spatial patterns of insect abundance are determined by characteristics of the landscape. In northeastern Missouri, the landscape is characterized by oak-hickory forest with relictual patches of oak savanna. We examined the abundance of five beetle (Coleoptera) taxa across the savanna-forest ecotones in Thousand Hills State Park, Adair County, MO. Pitfall samples were collected at three time periods (June, August 1993; June 1994) along three transects (11 traps each) that spanned savanna-forest ecotones in each of four savanna patches (only two patches in 1994; 330 traps total). Most (40-70%) of the 304 beetles were located in forested areas in both years; the savannas had the lowest beetle abundance. Our findings suggest that these beetles taxa respond to landscape characteristics at fine (<25m) spatial scales.
