"WALL JUMPERS"
The jumping spiders below are only two of various species that are found frequently on the walls
of homes and other human structures. The species at left is native to lands around the
Mediterranean. Apparently it was introduced accidentally into California several
decades ago, and it is now common in the Sacramento area of the state.
The Zebra Jumper below is common in northern
parts of Eurasia and North America
