NATURE KNOWLEDGE: Hickory Tussock Moth

Aug 2011 033come to me

This fuzzy little guy is a Hickory Tussock Moth caterpillar. Most caterpillars are discovered in mid to late summer. Usually, by then, they have reached a noticeable size from eating all season and growing from larva into full caterpillars. Below, is one common variety of Hickory Tussock Moth.

Lophocampa caryae

There are many varieties of Tussock Moths. Their caterpillars vary in appearance too. All are about 2 inches long and fuzzy/spiky in appearance . They love eating Hickory trees but will settle for Elm, Ash, Oak and Willow trees too. They sometimes can cause the defoliation of these trees.

weird 001The one above, was brought to me by my daughter who had found it so curious looking. Thankfully, she did not handle it directly. I found this warning when making the identification:

“The Hickory Tussock Moth caterpillar has poisonous hairs and spines that can cause skin rashes similar to poison ivy. If your child should rub his/her eyes or touches his/her nose after coming into contact with this caterpillar reactions can also include conjunctivitis (eyes), light sensitivity (eyes) and wheezing (nose).”

Under a microscope, those little hairs are barbed. Seems these little guys are “armed and dangerous” to most prey. Thankfully, most toads, small snakes and birds don’t mind a bit. We are very fortunate that Mother Nature holds everything in delicate balance!

PS.~ These caterpillars were photographed in New York State and Massachusetts. The link to the warning talks about Maine but they are here too!

  1. I’m very careful with caterpillars ever since we moved to France and discovered the ‘pine-processional’ – which also has hairs to beware of. They cause rashes, problems if inhaled and can seriously injure the tongue of an inquisitive dog.
    Your hickory tussock moth, and caterpillar are just beautiful!

    • Thank-you. I found the white ones so pretty but should always regard beauty, in Nature, as a likely warning. I appreciate your comment!

    • Every part of Nature fascinates me, but I am drawn to photographing insects and amphibians most often. Many people are not, at all, informed and I hope to help in that area with my NATURE KNOWLEDGE posts. Thanks for your question!

Tell me something good...
