Bold Jumping Spider (Phidippus audax)

Phidippus audax

The Phidippus audax, famous as 'Bold Jumping Spider'. Along with the P. regius, it is the most bred jumping spider in the world. More compact, stocky and omnipresent on the North American continent compared to the regius, it stands out for its invariably Black base coloration, decorated with white (or orange in juveniles) spots and stripes and spectacular metallic Emerald Green iridescent chelicerae. True to its name ('audax'), it is an intrepid and diurnal predator that does not hesitate to study the keeper's fingers or to jump on prey much larger than itself. Shares the same care, the very short longevity and the extreme visual intelligence of its Florida cousin.

Care, breeding and tankmates

Terrarium Setup: Animal Diversity Web reports grasslands, prairies and open woodlands as natural habitats. This is natural-history context, not a captive setup protocol.
Lighting and Heating: The source reports daytime hunting. This is field behaviour, not a captive lighting or heating parameter.
Humidity and Hydration: The source does not establish captive humidity or hydration parameters.
Feeding and Supplementation: Animal Diversity Web describes jumping spiders as carnivorous predators of insects and other spiders. This is field-diet context, not a captive feeding or supplementation protocol.
Compatibility and Coexistence: Animal Diversity Web reports solitary daytime hunting. This is behaviour, not captive grouping guidance.
Health and Common Diseases: The source does not establish captive health, handling, or veterinary protocols.
