They are easily distinguished from other spiders, by their unique eye arrangement, and general behavior. For instance, they don’t just walk, but rather, dart about so quickly from one spot to the next, that it’s hard to see them move!
The phidippus borealis is one of the prettiest spiders around for its small size – its colors are absolutely wonderful! You can find these spiders throughout the Pacific Northwest.

These small spiders will spin silk for drag lines, egg cases, and retreats, but do not build webs for capturing prey.

Of the 1,400 spider species in Canada, 120 or so, are jumpers. These are the ones discovered so far, but l suspect there are many more
