Insects emit “Silent but Deadly” toxic gases to immobilize prey!

The adult lays its’ eggs in a termite mound, and once they hatch, the tiny, ferocious and gaseous larvae are immediately able to locate the termites that are their prey.

After locating its’ victim, this young lacewing points it’s rear toward the termitestermite colony face and waves it around.  There is no noise and no warning smell.  The termite doesn’t even react or appear to be affected as the vaporous toxicant is emitted but in about three minutes the termite is immobile and the larva begin to liquefy and feed off of it.  Even if not eaten the termite dies in about three hours, making these gaseous emissions truly deadly.

Scientists performing studies on these gas producing insects cannot yet tell us why the gas is so deadly to termites and not to other insects.

This gives new meaning to “rear attack”.

Several other lacewing relatives perform similar “rear attacks”.  The species Chrysoperla Comanche , emits a droplet from it anal glands and waves it around if disturbed.  They have been observed, raising their abdomen over their heads placing a gooey droplet onto the head of an anchrysopidae-wallpapers-by-caroldegraffnoying ant.  It’s incredibly sticky and the ant will work long and frantically to remove it, forgetting all about the lacewing. This substance seems to be the same stuff that they use to adhere themselves to a leaf when they change from a larva into a pupa.

So, it’s obvious that this topic is no laughing matter to the termite, but it does make one smile as one remembers their own “Silent but Deadly” experiences.

Bye the way, here’s a fact that may make you feel a little less sorry for the termite.  Termites are the top methane producers globally. They even beat cows in their production of methane and their contribution to “Global Warming”!
