Walnut Orbweaver

Nuctenea umbratica

The Walnut Orb-Weaver Spider hides itself beneath bark and within crevices of posts and fences throughout the day. This particular specimen was located on a London plane tree. This spider is active at night, building an orb web between its refuge and adjacent vegetation. During daylight hours, the web is generally vacant, while the spider remains concealed in close proximity. Adults of both sexes are mainly observed from late spring to autumn; however, females, and occasionally males, may be found during the winter months.
