Which organisms are most beneficial to humans without us realising? | Insects
I was recently beset by a plague of clothes moths. After hours of research, I discovered the miracle that is the parasitic wasp, or Trichogramma evanescens – near-microscopic beasts that you can order online (in sachets of 2,000 wasps!), the life’s calling of which is to destroy clothes moth eggs.
It made me wonder: is there anything else in our daily lives that is so beneficial to us, but which few of us have heard of – or realise is there?
