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.
