Phidippus otiosus? - Phidippus otiosus
Herndon, Fairfax County, Virginia, USA
September 16, 2006
This spider greeted me at the door when I returned from a round around the yard with my camera. I hadn't seen this type of jumper before. I just went through every page in the jumping spiders section here, and the closest resemblance is this shot of Phidippus otiosus, white and brown with metallic green on top of the abdomen like mine had:

This
is most likely an immature P. princeps, as the two pairs of white markings near the spinnerets (spots 3 and 4) are not typical of otiosus or similar species.
In case you're interested, spots 1 is near the carapace (head), and spots 2 is basically in the middle of the abdomen. Spots 2 is often fused, appearing as a single spot.

Interesting -
I see that most of the specimens in BugGuide are fairly plain. Do they lose the markings as they mature? Or are females plain and this is a male?

Size?
Do you remember the size of this one? I'm rearing a few P. princeps right now and haven't seen markings like this, but mine weren't from the egg sack so I may have missed this stage if it existed.

Yes, appearance of jumpers can change greatly between molts. When my captive princeps were collected they looked like this one:


And on their very next molt they looked like this:


After their next molt the abdomen markings are almost completely invisible under their fur.

Fascinating; thank you!
This one was maybe 3/8" - 1/4", if I remember correctly. I need to remember to carry something for size around with me!

Yes
they do lose the markings as they mature.
