The hickory tussock moth caterpillar<\/strong> is a white, fuzzy caterpillar with black markings and long hair tufts. It is the larval stage of the hickory tussock moth, Lophocampa caryae<\/em>, also called the hickory tiger moth<\/strong>. Although it looks soft, this caterpillar should not be handled with bare hands. Its hairs can cause itchy rashes, skin irritation, and allergic reactions in some people. It commonly feeds on hickory, walnut, pecan, oak, ash, elm, willow, maple, and related trees.<\/p>\n\n\n\n

What Is a Hickory Tussock Moth Caterpillar?<\/strong><\/h2>\n\n\n\n

The hickory tussock moth caterpillar is a hairy caterpillar found in the eastern half of North America. It belongs to the tiger moth group and is best known for its white body, black tufts, and irritating hairs.<\/p>\n\n\n\n

It is not a butterfly caterpillar. It becomes a moth, usually called the hickory tussock moth or hickory tiger moth. The adult moth is less noticeable than the caterpillar and is not the main safety concern.<\/p>\n\n\n\n

Hickory Tussock Moth Caterpillar Identification<\/strong><\/h2>\n\n\n\n

    Is the Hickory Tussock Moth Caterpillar Poisonous?<\/strong><\/h2>\n\n\n\n

    The hickory tussock moth caterpillar is often called poisonous, but the main problem is its irritating hairs. Penn State Extension explains that exposure to the caterpillar\u2019s hairs generally causes a localized rash and itching.<\/p>\n\n\n\n

    It does not sting like a flannel moth caterpillar or inject venom with large spines. However, the hairs can break off in the skin and cause irritation. Some people may react more strongly than others.<\/p>\n\n\n\n

    Safety Notes<\/strong><\/h3>\n\n\n\n
      \n
    • Do not handle it with bare hands.<\/li>\n\n\n\n
    • The hairs may cause itchy rash.<\/li>\n\n\n\n
    • Sensitive people may have stronger reactions.<\/li>\n\n\n\n
    • Keep children from touching it.<\/li>\n\n\n\n
    • Keep pets from chewing or eating it.<\/li>\n\n\n\n
    • Wash exposed skin after contact.<\/li>\n<\/ul>\n\n\n\n

      Hickory Tussock Moth Caterpillar Sting or Bite<\/strong><\/h2>\n\n\n\n

      People often search for \u201chickory tussock moth caterpillar sting\u201d or \u201cbite,\u201d but this caterpillar does not truly bite or sting like a wasp. The reaction usually comes from contact with irritating hairs.<\/p>\n\n\n\n

      The hairs can stick into the skin and cause itching, redness, or a rash. This can feel like a mild sting, but it is different from venom injection by flannel moth caterpillars.<\/p>\n\n\n\n

      Hickory Tussock Moth Caterpillar Rash<\/strong><\/h2>\n\n\n\n
      \"Hickory<\/figure>\n\n\n\n

      A rash from hickory tussock moth caterpillar contact may appear after touching the caterpillar or after hairs get on skin, clothing, or surfaces. University of Maine Extension notes that hairs from many tussock caterpillars can cause an itchy rash.<\/p>\n\n\n\n

      Rash Symptoms<\/strong><\/h3>\n\n\n\n
        \n
      • Itching<\/li>\n\n\n\n
      • Red bumps<\/li>\n\n\n\n
      • Mild swelling<\/li>\n\n\n\n
      • Burning or prickly feeling<\/li>\n\n\n\n
      • Irritated patches of skin<\/li>\n\n\n\n
      • Rash where the caterpillar touched<\/li>\n\n\n\n
      • Stronger reaction in sensitive people<\/li>\n<\/ul>\n\n\n\n

        The rash is usually localized, but severe allergic symptoms should be taken seriously.<\/p>\n\n\n\n

        Hickory Tussock Moth Caterpillar Rash Treatment<\/strong><\/h2>\n\n\n\n
        \"Hickory<\/figure>\n\n\n\n

        Most mild reactions can be managed by removing hairs and calming the skin. Cleveland Clinic advises washing the area, using tape to remove leftover hairs, applying ice, and using treatments such as calamine lotion, baking soda paste, hydrocortisone cream, or oral antihistamines if symptoms worsen.<\/p>\n\n\n\n

        Basic Treatment Steps<\/strong><\/h3>\n\n\n\n
          \n
        • Do not scratch the rash.<\/li>\n\n\n\n
        • Wash the area with soap and cool water.<\/li>\n\n\n\n
        • Use tape gently to lift off hairs.<\/li>\n\n\n\n
        • Apply a cold compress or ice pack.<\/li>\n\n\n\n
        • Use calamine lotion or hydrocortisone cream for itching.<\/li>\n\n\n\n
        • Wash clothing that may contain hairs.<\/li>\n\n\n\n
        • Get medical help for eye exposure, breathing symptoms, swelling of the face, or severe reaction.<\/li>\n<\/ul>\n\n\n\n

          This is general first-aid information, not a medical diagnosis.<\/p>\n\n\n\n

          Hickory Tussock Moth Caterpillar and Dogs<\/strong><\/h2>\n\n\n\n

          The caterpillar is not a good snack for dogs or cats. Pets may get irritating hairs in the mouth or carry hairs on their fur. If a dog eats one, it may drool, paw at the mouth, vomit, or act uncomfortable.<\/p>\n\n\n\n

          Pet Safety Tips<\/strong><\/h3>\n\n\n\n
            \n
          • Keep pets away from fuzzy white caterpillars.<\/li>\n\n\n\n
          • Wipe paws and fur after walks in infested areas.<\/li>\n\n\n\n
          • Do not let dogs chew caterpillars.<\/li>\n\n\n\n
          • Wash pet bedding if hairs may be present.<\/li>\n\n\n\n
          • Call a vet if your pet shows strong mouth irritation, vomiting, or distress.<\/li>\n<\/ul>\n\n\n\n
