Nuctenea umbratica
The walnut orb-weaver spider is very wide and flattened, with a leathery skin. Its color ranges from red brown and grey brown to black with a dark, yellowish to yellow-greenish leaf-like fleckled marking on its opisthosoma, where small dents are visible. These are the onsets of muscles that flatten the abdomen. Female N. umbratica can reach up to 15 mm in size, the males grow only up to 8 mm.
The Walnut Orb Spider hides away during the day in nooks and crannies or under bark, close to its web and it only emerges to secure any prey that gets trapped in the web.
