Marpissa muscosa

Marpissa muscosa is a species of jumping spider.

Marpissa muscosa, female.

The species builds a kind of nest under the bark of dead trees. Up to 100 of these nests can occur side by side. As other species of the Marpissa spiders it demonstrates a social hierarchy: weaker animals will acknowledge their inferiority by strutting their front legs and slowly retreating from the scene.[1] Early environmental conditions shape personality types in the developing spiders.[2]

Distribution

M. muscosa lives in the Palaearctic.

Though rare in England, it is found throughout the country, more in the south and east. The species is widespread in northern Europe.
