  2. I found a large green caterpillar in our backyard today that sure seems to be a Luna Moth caterpillar. 3" plus long and quite plum. Little dots of color and hair coming out of the dots. Olympic Peninsual

    1. Lunas don't occur in the west. Look up images of Polyphemus moths, Antheraea polyphemus, the larvae are very similar and it is a common species across the US, feeds on maple and oak.
