phora and at least some of the linyphiids place sticky silk in their 
webs — Cyrtophora in the mesh just above the platform (Kull- 
mann 1958), and the linyphiids in the sheet and the mesh above 
(Kullmann 1964* pers. obs.). Diguetia albolineata and D. canities 
webs are similar to A. tesselata webs in lacking sticky silk (pers. 
obs.). Achaearanea tesselata is unique in resting above the platform 
and dropping through it to attack prey, as all the others rest on 
surfaces connected to the lower surface of the platform.
