Life Cycle
Odonate exuviae are often found to be occupied by this species (and sometimes other salticids) along the Pacific Coast (1).
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.
