They come out mostly at dusk/dawn but have been known to attack later in the day depending on how hungry they feel or time of year too, which makes it hard to predict when they may strike next. They will consume almost anything pine, rose, lilac, rhododendron, hosta, violet's, etc., as well as the leaves of these plants too, which is just downright frightening in my opinion.
