When disturbed, Uloborus glomosus either remain in position at the hub of their orb-webs, jump from the web, move to the edge of the web, or shake the web . The time of day influences which of these behaviors is expressed . Spiders tend to jump in the afternoon and the evening but not in the morning . In the morning they tend to move to the edge of the web or remain in position . The tendency to shake the web is approximately the same throughout the day. Ambient temperature appears not to be the principal factor explaining the differences in jumping, moving to the edge, and remaining in position . Historical differences in the activity patterns of various spider predators may have influenced the time-related expression of disturbance behavioral patterns.
