Phidippus otiosus is a species of jumping spider that is found in southeastern North America. It is primarily a tree-living species.[1] Females reach a body length of about 16 mm. Its iridescent chelicerae can range in color from purple to green.

Life cycle

[edit]

Females position their single egg sac under the bark of oak and pine trees.[2] These are laid from December to February in South Carolina, and from January to June in Florida. The egg sac can hold anywhere from 19-150 eggs, and the spiderlings (slings) will disperse between January and February.[3] The spiderlings mature during fall.

Systematics

[edit]

Phidippus otiosus is grouped with the closely related species P. californicus, P. pius and P. regius in the otiosus group.[4]

Distribution

[edit]

Phidippus otiosus naturally occurs in the southeastern United States from Florida and Texas to North Carolina.[5] However, this species is sometimes exported with plants such as Tillandsia, and has been found in countries as remote as Sweden[6] and Germany.

Name

[edit]

The species name is possibly derived from Latin otium "leisure, peace, quiet" + the suffix -osus "full of, prone to", or from Ancient Greek oto- "ear", referring to the tufts of black hair.

A common name for this species is Canopy Jumping Spider.
