Marpissa muscosa is a species of jumping spider.

Marpissa muscosa, female.

Females reach about 8–13 mm length, males only 6–8 mm. Both sexes are coloured grey to brown. The whole spider has a furry appearance and is flattened in shape.

The species builds a kind of nest under the bark of dead trees. Up to 100 of these nests can occur side by side. This spider demonstrates a social hierarchy: weaker animals will acknowledge their inferiority by strutting their front legs and slowly retreating from the scene.[citation needed]


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.
