Yellownecked caterpillar
Datana minnistra

  • Young larvae feed in groups and skeletonize the leaves,i.e.,eat the leaf tissue except the veins
  • As larvae mature, they become solitary feeders and feed along the leaf margins, eventually consuming the entire leaf.
  • Larvae are active from late July through early September
  • Larvae have black head with a striped body covered with fine white hairs and their identifying orange yellow rectangular spot behind their heads. There are two color phases, black with orange-yellow stripes and orange- yellow with red-orange stripes.
