Larvae of the leafminer Chromatomyia fuscula attack many wild and cultivated grass species, including cereals, in Europe (Spencer 1969, 1991; Griffiths 1980) and are considered a major pest in parts of Fennoscandia (Spencer 1973; Andersen 1989a). However, in North America this species has been reported only on non-cereal grasses (Spencer 1969, 1991; Griffiths 1980). Therefore in 1994 a survey was undertaken in the region around Quebec City to determine if C. fuscula was truly restricted to non-cereal grasses or if, as in Europe, it also attacked cereals.
