Dionycha (plant)
The Dionycha are a clade of spiders (Araneomorphae:Entelegynae), characterized by the possession of two tarsal claws with tufts of hairs (setae) beside them, which produce strong adhesion, enabling some species to climb glass. The Circumscription (taxonomy), circumscription of the group has varied widely; a 2021 analysis resulted in about 20 families, including Salticidae (jumping spiders), Gnaphosidae (ground spiders), and Clubionidae. The Dionycha are considered to be a subgroup of the larger RTA clade. Most species hunt their prey instead of building webs. There are no cribellate members in the Dionycha.Griswold ''et al.'' 1999 Today it is thought that the reduction of the third claw present in ancestral spiders evolved several times independently, so this alone is not a criterion that defines the clade. Families In 2021, a group of several spider taxonomists published a major study of the phylogeny of Dionycha, using genetic and phenotypic data. It included the families lis ...

Marpissa Muscosa
''Marpissa muscosa'' is a species of jumping spider. On average, females have body length ranging from 7.5–14mm, whereas males have a body length ranging from 6–8.1mm. 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. 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. Early environmental conditions shape personality types in the developing spiders.Jannis Liedtke, Daniel Redekop, Jutta M.
