Last week’s question was: What insect caused this feeding damage on a canola leaf?
This is from the harlequin bug. This is a member of the stink bug family, Pentatomidae. Harlequin bugs are pests of a wide range of plants in the Brassica family (cabbage, collards, kale, broccoli, canola, etc.). The damage pictured above is caused by feeding as the bugs pierce the leaves and suck out the sap. Take a look at this page for more info.
Here is this week’s question: What kind of butterfly will emerge from this chrysalis found in a rapeseed field?
