Some species build extensive webs with an upper retreat tangle and connecting threads to scaffolding. This supports the ladder-like catching platform that is glued to the ground.
Hickmania, Progradungula (a large spider with long legs like Hickmania,[1]), and Macrogradungula are the only cribellate genera of the family.
