Despite being annoyed at the terse demanding tone of this query, we are posting a relatively lengthy answer, however our personal reply was equally brief. This is a White Marked Tussock Moth Caterpillar, originally Hemerocampa leucostigma and now identified as Orgyia leucostigma. It is a pest on most shade and ornamental trees. They can become so numerous that they defoliate trees. Though the caterpillar is quite beautiful, the moth is small and inconspicuous.

    Hi,
    Just came on this web site. I also have this white marked tussock moth caterpillar all over my hop plants. I also am a home brewer. These hops have been here for 5 to 10 years and this is the first year I have seen them and they are very abundant, so I am highly confident they came from some other source as we have an extensive garden. We live in central Michigan 5 miles north of East Lansing in Bath. I wonder what adverse affects they have caused since this post is 2 years old.
    Thanks Tom D.
