Another one of these - Eris militaris
Willamette Valley, lane County, Oregon, USA
June 30, 2014
This is the fourth one of these I've videographed, they are well distributed around here but hard to find. All my subjects have been near running water, within 20 meters.

I think they are Pelegrina aeneola and want to ID them without capturing or killing one, which to me would be like strangling a leopard cub. Eventually someone who is sure about Oregon salticids will see my images. So here is the youngest of the bunch. Dig the gold central stripe!

If you decide you want to try a capture, use a water bottle.
Sometimes they can be coaxed into them, or even they are curious enough to venture in to see what the space is all about. I like to take a pin and poke holes all around the bottle to provide a little air flow. I've made a funnel from a rectangular postit note that I move my jumpers from a water bottle to a tic tac container (and back to the bottle again) with. Tic tac containers make both great holding spots as well as a spot to photograph them in. Then just pop the top open and set it down to release when you're done. No harm done to the spider.

you can get
closeups of palps or epigynum in a tic tac bottle?

I can catch them, but I've always figured I'd have to kill or etherize them to get an ID-worthy shot.

Well...
maybe not. I've gotten some great epigynum photos through the tic tac container, at least well enough to tell male from female, and palps are also easily photographable... but I'm sure you'd want better photos than you could get through a tic tac container. You're probably right though for an ID-worthy shot. I guess I misunderstood your comment.
