Last week the question was: What is this little caterpillar on the underside of this cabbage leaf?
This is a diamond back moth larva or DBM. This is one of the most common pests of brassica crops. They’re small and only get to be about a half inch long before they pupate, but their populations can build quickly and cause a lot of damage. The “window pane” feeding pattern (where they leave the upper cuticle of the leaf intact) is a tell-tale sign of DBM. Take a look at the Southeastern Vegetable Crop Handbook for info on thresholds and control options.
Here is this week’s question: What is this?
