Abstract: We developed this handbook for forestry professionals, land managers, and homeowners to help them identify the most common adult and larval sap beetles found in oak wilt mats in the North Central States. Although the photographs depict the natural color of adults, preserved specimens may not have exactly the same color as those in the pictures. All sizes given are length ranges and mean lengths based on measurements of our specimens using a light microscope with an ocular micrometer. The brief written descriptions are not intended to be taxonomically complete, but to pinpoint the features most useful in distinguishing species from one another. The descriptions are largely based on those of Parsons (1943).
