Marpissa muscosa

The species builds a kind of nest under the bark of dead trees.

As other species of Marpissa spiders, it demonstrates a social hierarchy: weaker animals will acknowledge their inferiority by strutting their front legs and slowly retreating from the scene.

These spiders are typically found on spruce and pine trees, under bark, in moor- and heathland, and around buildings.
