 P. schultzi , along with a large variety of spiders and insects , is often found in the dense , large webs of the <unk> <unk> karschi ( about 15 millimetres long : 31 ) , which are especially abundant in partly cleared secondary bush where rain forests have been cut down , and usually about one metre above the ground . A survey of one area suggested that there is about one P. schultzi per three I. karschi webs . P. schultzi is also found in its own web and those of other spiders , on tree trunks and the walls of buildings , and in leaf litter . : 30 @-@ 32
