We found four different spider traps, from different individuals of the same species of spider, built by leaves of three tree species. In all four cases, two leaves (one of the same tree species) were woven together with a spider web (Fig. 2 B) and the spiders (Olios sp.) were hiding at the far end of the leaves. To weave the leaves together, the extremities of the leaves (inner and outer part) were pulled together by silk and became close to each other. The traps were open at the petiole part of the leaves, enabling prey climbing up the stem of the tree to enter. The spiders were well-hidden at the base of the trap (i.e. the tip of the leaves) and not visible from the entrance. The spiders do not seem to have a strong preference for a single trees species and the height from the ground also seems variable from those observations.
