Yellownecked caterpillar
Datana ministra

  • Young larvae skeletonize leaves, i.e. eat the leaf tissue between the veins so that it appears lace-like, gregariously (in groups)
  • Older larvae eat entire leaves, except the leaf stalk; feed singly from leaf margins
  • Yellow and black stripes along body with black head; fine white hairs over entire body; head and tail get lifted in typical “U” appearance when distressed
  • Damage seen July into September
