Like a mindless zombie controlled by a menacing overlord, the spider scampers back and forth, reinforcing its silky web. Not long from now, the subservient arachnid will be dead, its web transformed into a shelter for the spawn of the creature that once controlled it, according to a new study.

No, this isn't science fiction; it's the somewhat terrifying (but very real) tale of the orb-weaving spider Cyclosa argenteoalba and the parasitic wasp Reclinervellus nielseni, two species that carry out a strange relationship in Hyogo prefecture, Japan.
...
That's why R. nielseni doesn't just direct its host to build a resting web; it instructs the spider to build a superstrong resting web, one chock-full of reinforced threads that hold the web — and the wasp-filled cocoon at its center — in place for long stretches of time, the researchers found.

Using a tensile machine, Takasuka and his colleagues tested the breaking forces (how much force a material can handle before breaking) of the radius and frame silks used to construct a so-called "cocoon" web and found that they were at least 2.7 times greater than the breaking forces of the silks that made up both the orb and the resting webs of C. argenteoalba.

The researchers suspect the wasp larva releases a hormone into the spider that mimics the signal to molt. With precedents in nature, perhaps the Zombie Apocalypse isn't so far-fetched after all.

    Better than weaponize wasps for the same purpose, don't you think?
    Be it for the only reason I'm yet to see humans secreting web spiders for the wasps progeny.

    I see you've never eaten natto [wikipedia.org].

      Indeed, I haven't. But somehow I have a hunch the slime in natto isn’t produced by humans, am I wrong?

        Oh, it's not about how it goes in.
