When life is but a stream, insects need something extra-sticky to survive
Mercifully for these minuscule creatures , they’re hatched into the world with something of a superpower for surviving the tough terrain: a versatile silk, dispensed from glands under their chin. Natural-born builders, the larvae deploy the sticky substance to fashion cases for themselves out of small pebbles that guard them against careening objects, and provide camouflage and protection against predators.
This entry in the science-documentary series Deep Look takes a quick dive into the lives of these impressive improvisational engineers, including how their waterproof adhesive has inspired bioengineers hoping to create less-intrusive internal stitches for the human body.
