The Potato Capsid (a true Miridae bug) is a minor pest of potatoes but by way of compensation, it is just as happy feeding on nettles, thistles, ragwort, clover and, as seen upper right, on Hedge Mustard.
The Common Capsid is a very similar green bug but, the key to positive identification of the Potato Capsid lies in the two brown dots on the pronotum region just behind the head.
Early instars tend to appear uniformly green but after the final metamorphic moult the adult insect emerges quite pale and will take some days to develop mature colouration.
