Cross-Striped Cabbageworm
Return to insect pests
Cross-striped cabbageworm (Evergestis rimosalis) larva is bluish-gray in color with numerous black stripes running cross-wise on its back. Below the transverse stripes on each side is a black and yellow stripe along the length of the body. The larva reaches 3⁄4 inch in length. The larvae drop to the soil to pupate in a tight cocoon just below the soil surface. The scale-like eggs are light yellow and laid in masses of 20 to 30 on the undersides of the leaves. The moth is yellowish-brown to brown with dark zigzag markings and has a wingspan of about 1 inch. Larvae feed on all tender parts of the plant, but prefer terminal buds. Young leaves and buds are often riddled with holes.

Management:
- Because eggs are laid in clusters, infested plants are often found close together. Sprays used to control other caterpillars on these crops are usually effective against cross-striped cabbageworm. Bt insecticide sprays early can be very effective against this pest.
