Details about map content are available here.


A serious, leaf-mining pest species that feeds on crucifers (canola, mustard, radish, cabbage, broccoli). In March 2013, it was reported from bell pepper plants in the Fraser Valley, a crop it normally avoids.

This is a narrow-looking, small, grey/brown species of moth (about 1/2" in length) with white/yellow (diamond) patterning on the forewings wings that is noticeable when the wings are folded. Larvae are green. The species is cold-intolerant but can appear in large numbers in Canada in the spring (BC Ministry of Agriculture 2013).
