Differences in web structure and cephalothorax features suggest that Hyptiotes cavatus should exert more force while monitoring its vertical triangle-web than Uloborus glomosus exerts while hanging beneath the hub of its horizontal orb-web. When this hypothesis was tested by measuring the force that instars of each species exerted on a horizontal thread, Hyptiotes cavatus was found to exert significantly more force throughout development than did Uloborus glomosus. This relationship holds when either first femur length or body weight is used as an index of spider size. 4 pp., 5 figs, 4.
