Walnut orbweaver — size comparison — facts and sources
The walnut orbweaver occurs in Europe and parts of Asia. In natural habitats it uses loose tree bark, especially on dead trees, but also inhabits fences and building crevices. Its dark abdomen, bearing a leaf-like pattern, is broad and distinctly flattened. This shape helps it squeeze into narrow retreats.
It usually remains hidden by day. After dark it builds or occupies an orb web in which it catches insects. The centre of the trap may be offset towards its retreat.
Adult females are larger than males. Young individuals are more easily confused with other dark orbweavers.
