Figures 1-2. Web of Uloborus conus. 1. Side view showing the rim sticky spiral 
(RS), inner orb (I), cone (C) with jagged sticky spiral (CS) on a framework of radii 
and non-sticky spiral, and cone radii (CR) converging toward a central guy thread. 
Note that 2-3 cone radii are attached together to form one thread which attaches to 
the cone guy thread, and that these attachments are dispersed along the guy thread so 
that there is no single apical point to which all cone radii attach. 2. Top view 
showing typical Uloborus - type hub and non-sticky spiral of the inner orb. The cone 
with its jagged sticky spiral (CS) is seen through the plane of the orb. Note the gap 
between the non-sticky spirals of the cone and inner orb on the one hand and the rim 
sticky spiral on the other. The cone sticky spiral can be seen as a continuation of the 
rim spiral (arrow points to beginning of cone sticky spiral).
