Orgyia antiqua

The larvae hatch early in the spring, as soon as foliage starts to appear. They are easily recognized by their hornlike tufts of hair-like setae. Four toothbrush-like tufts occur along the back, and hair pencils project from the sides at the front and at the back. The body is dark grey to black, and red tubercules are along the sides and back. They have defensive glands at the back, and wipe their setae against them to charge them with toxins.
