Question of the Week: DBM

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?
