The map shows the predicted date of first adult emergence of bluegrass billbug in Iowa, based on actual temperatures recorded this spring. Bluegrass billbug is recognized as an occasional pest of Kentucky bluegrass. Although it prefers Kentucky bluegrass (as its name implies), the bluegrass billbug also feeds on perennial ryegrass, fescue, and timothy.
