⚠️The hickory tussock moth caterpillar is nature’s reminder to look, don’t touch! ⚠️
The hickory tussock moth caterpillar may look cute and harmless with its fluffy white body, bold black markings and long black hairs, but looks can be deceiving!
This native species is one of the more distinctive caterpillars found in Southern Ontario. As it prepares for winter, it feeds on the leaves of hickory, walnut, ash, elm, maple, willow, and oak trees before spinning a cocoon.
While visually impressive, this is one caterpillar that is best admired from a distance. Its venomous hairs can cause skin irritation similar to poison ivy, with reactions ranging from mild redness and itching to swelling and discomfort.
If skin contact occurs:
• Wash the affected area with soap and water as soon as possible
• Avoid rubbing or scratching the skin
• Apply a cold compress or ice pack to help reduce any discomfort and swelling
• Use calamine lotion or an over-the-counter anti-itch product if needed
• Seek medical attention if you experience signs of a severe allergic reaction
To help prevent skin contact, wear clothing that covers the skin such as long sleeves and pants. Remember to keep pets away, as contact can irritate their mouth, nose and paws.
The hickory tussock moth plays an important role in forest ecosystems and is a remarkable example of nature’s beauty. Just remember, not everything fluffy is friendly! 🐛
