Technical Abstract: Coleomegilla maculata lengi (Coleoptera: Coccinellidae) is native to the eastern half of the United States. However, we recently collected several individuals of this lady beetle from =250 km beyond the western edge of its reputed range. We hypothesized that new records could indicate either that previous range characterization failed to include pre-existing collection records further west, or alternatively, that C. maculata lengi has recently expanded its geographic range. In order to test these hypotheses, we searched several institutional insect-collection databases for records of C. maculata lengi outside of its putative geographic range. We found many earlier records of C. maculata lengi beyond its reputed geographic range, and report those records here. Accordingly, the records establish that previous range characterization.substantially underestimated the geographic distribution of C. maculata lengi in North America.
