We’re not 100% sure, but believe that this is an extremely gravid (filled with eggs) female Western Lynx Spider. Similar to wolf spiders and jumping spiders, Western Lynx Spiders are active hunters that are fast runners and leapers with good vision. Rather than hunting on the ground, they are referred to as “foliage hunters” — often lying in wait to capture prey on plants, trees, and bushes. Their long, spiny bristles form a “basket-like” cage that may assist in capturing prey and providing the spider with some protection. Photo by Rose Marchak on 7/22/19 in Missoula, MT.
