The mix of black and white markings on the Salt-and-pepper Looper create a pattern reminiscent of inkblots.
Salt-and-pepper Loopers have black and white tufts of hair that poke out from the thorax area and even between the wings. Some individuals have collars of brown hair near the head, but overall, this moth is black, white, and shades of silver and gray. An intricate black patch in the center of the wings is framed in bright white marks that resemble dripping paint. An overlay of silver is common in eastern and northern populations. The hindwings are a pale brown color that have a dark brown border.
Loopers have caterpillars that form loops, or rings, with their tubular bodies as they crawl. The feet come up right behind the head, bending the body upward into a circle shape. This green caterpillar feeds on conifer trees such as fir, hemlock, spruce, and pine. They are a minor pest because of their feeding habit, but they rarely eat enough on a tree to harm it. Look for Salt-and-pepper Loopers all summer long in mountainous, or elevated, areas where evergreens are growing. They are nocturnal and will come to lights at night, but they are also active in the daytime, allowing for plenty of viewing opportunities.
