Congratulations to Sara Collins for correctly identifying last week’s non-pest as Polyphemus moth. This particular specimen is a female. She will emit a powerful pheromone that will attract any male from up to several miles away. Polyphemus prefer to feed on elm, birch, willow, oak, and hickory. They do not feed as adults and thus do not live long.
