I love the slight golden tinge on its carapace and abdomen. A closer look reveals a streak of blue on the femur. This makes the spider even more attractive. Using innovative experiments, local researchers have shown that females of another jumping spider species (Cosmophasis umbratica) would spend a longer time observing ultra-violet (UV+) males than UV- males regardless of which male display more actively. This suggests for that species, male UV influence plays a role in female-mate choice. Perhaps similarly, the iridescent bluish leg femora would help a male Banded Phintella in attracting the opposite sex.
Banded Phintella can be encountered at gardens as well as forested habitats.

Enjoyed your posting and the photos. I have many photos myself of jumping spiders, surely my favorite of the spiders family.
