“The webs of Black House Spiders are constructed from cribellate silk, which is not sticky but is made from multiple combed fine strands and is extremely efficient at snagging the spiny legs of insects. The webs are in the form of lacy silk sheets, which spread out around one or more entrances to the spider’s retreat.”
