Leaves Eaten by Parsleyworms
Parsleyworms are large, strikingly colored 2 inch caterpillars. Green with yellow-dotted black bands across each segment, they emit an odor and project orange horns when startled. They feed on dill foliage, often until only the stems remain.
Before destroying a parsleyworm, be aware that it is the larvae of the black swallowtail butterfly. To preserve it and your dill move it to a member of the parsley family that you can spare, such as carrot, parsley, parsnips or the common weeds, wild carrot or Queen Anne’s Lace.
Parsleyworms are easy to spot in the early morning, handpick, drop into a plastic bag and discard in the trash. Control bad infestations with Bacillus thuringiensis or Bt. Dust or spray foliage surfaces so that feeding caterpillars will ingest it. They will sicken, stop eating and die in a day or two. Because Bt washes off with rain, use it again if the caterpillars are still active.
