  • Our parasitized caterpillar has spent the last 12 days gorging itself.
  • It now appears profoundly obese, but this is not all fat.
  • The Glomerata wasp larvae lie just under its skin.
  • Each is the size of a grain of rice, but together they account for over a third of the caterpillar's weight.
  • The larvae have not yet finished growing and need to keep their host alive.
  • So although they feast on the caterpillar's blood, they have been careful not to touch a single one of its vital organs.
  • This uneasy truce will not last.
  • Within days the larvae are fully matured.
  • Suddenly they begin to stir into action.
  • For the past two weeks this surrogate womb has protected them, but now they no longer need it.
  • To complete the next stage of their life cycle they must break out.
  • The caterpillar's thick skin should be a solid barrier to the parasitic wasp larvae, But as their bodies have grown they have developed tiny saw-like teeth.
  • These jagged jaws are for one job only, cutting Their way out.
  • Stroke by stroke the larvae slice through the tough layers of skin.
  • At The same time they release chemicals that paralyze the caterpillar.
  • As the larvae break through there is nothing it can do.
  • Free at last, the larvae enter a new phase of development.
  • They swiftly spin silken cocoons.
  • These will provide the perfect environment for their final transformation.
  • But ironically one of the greatest dangers the larvae will face is being themselves impregnated by other species of parasitic wasp.
  • Incredibly the wounded caterpillar helps them out.
  • Usually A caterpillar would spin a silken blanket to make its own cocoon, but the parasitized caterpillar spins his blanket on top of the wasp cocoons, giving them an extra layer of protection.
  • Scientists believe the same wasp virus that infected it weeks before has now invaded the caterpillar's brain and caused this bizarre corruption of its normal behavior.
  • Amazingly the caterpillar's natural aggression is now also exploited by the wasp virus.
  • The caterpillar becomes a bodyguard, actively protecting the cocoons from other parasites.
  • It will watch over them unceasingly until it eventually starves to death.
