Identification

Vagabond crambus is a medium-sized moth but one of the largest grass veneers. It occurs across the United States and southern Canada. It is common in Minnesota. Adults are found in grasslands, fields, and gardens. Larvae feed in the spring on fast-growing grasses and grains, including wheat and rye. They are not considered serious pests.

Adults are 1116 (18 mm) in length and have a wingspan of ¾ to 1916 (20 to 39 mm).

The forewings are pale tan. They are sparsely to densely peppered with dark scales between the veins creating streaky patterns. There are no dark lines crossing the wing. The outer margin has seven black dots, one at the end of each vein. The fringe is variable. It may be gray or almost black, and often has some white. The apparent color may be affected by the angle of the light.

The antennae are slender and thread-like. The finger-like sensory organs (palps) attached to the mouth are very long and densely hairy. They are projected forward, appearing like a fuzzy snout.

The caterpillar ¾ to 1 long. It is green to brown with dark spots, coarse hairs, and a brown head.
