Marpissa muscosa 
Scientific classification Kingdom: Animalia Phylum: Arthropoda Class: Arachnida Order: Araneae Family: Salticidae Genus: Marpissa Species: M. muscosa Binomial name Marpissa muscosa
(Clerck, 1757)Marpissa muscosa is a species of jumping spider.
Females reach about 8–11 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 has a hierarchy: weaker animals will show their inferiority by strutting their front legs and slowly receding from the scene.[citation needed]
Distribution
M. muscosa lives in the Palaearctic.
It is uncommon but widespread in England, more frequent in the south and east. It is widespread in northern Europe.
