 While most jumping spiders focus accurately up to about 75 cm away , P. schultzi responds to a maximum of about 10 cm in good light , and ignores everything in very subdued light . For prey , P. schultzi prefers web @-@ based spiders , then jumping spiders , and finally insects . The females of P. schultzi and other Portia species build " capture webs " to catch prey , and often join their own webs on to web @-@ based spiders to catch the other spiders or their prey .
