an orb weaver can produce SEVEN different types of silk using different combinations of silk glands. Some types are sticky, others are not, it all depends on what the spider is trying to get done. Think about: the spider has to assess the situation, then somehow express a combination of glands to produce the exact type of silk it needs to deal with it.

And that's setting aside the process by which they build those magnificent webs. Watch an orb weaver build a web and then ask yourself what other arthropod does anything even remotely like that.

Some scientists now believe that early orb weavers were a TOTAL CATASTROPHE for the first flying insects that evolved. They say that shortly after arthropods crawled out of the sea, some sprouted wings and began to fly, and then these orb weavers came out of nowhere and started trapping them in yuge webs. Even today orb weavers catch more insects than they can ever possibly eat
