Range
KS-TX-CA
Habitat
On shrubs and vines and in fields. Best know as a common resident in vineyards.
Food
Insects and smaller spiders. Said to like thrips and small flies, but not leafhoppers
Life Cycle
Odonate exuviae are often found to be occupied by this species (and sometimes other salticids) along the Pacific Coast (1).
Remarks
The body is covered in iridescent scales which flash either green or gold in strong light (often doesn't show up well in photographs). This iridescence has been explained as mimicking of certain beetles, but more recently it's been suggested that it may be for mimicking of water droplets. Sassacus vitis in Florida, Mexico, and Central America often have white patches behind the posterior lateral eyes and longitudinal white stripes on the abdomen:
