Horsehair Worms

Horsehair Worms or Gordian worms is a common name used for parasitic animals of phylum Nematomorpha. They are found  in damp areas such as watering troughs, streams, puddles, and cisterns. Most species have a body length ranging from 50 to 100 centimeters and body diameter from 1 to 3 millimeters. In extreme cases they can even reach up to 2 meters long.  The adult worms are free living, but the larvae are parasitic on beetles, cockroaches, orthopterans, and crustaceans.

Yes, very interesting!
yours are huge!!
I found out about these worms a couple of years ago as I found some in my swimming-pool!
I did some research, talked to the chemist and conclusion:
The larvae develops inside a host, usually a cricket, a hopper.... and as they reach the time to breed, they secrete a "toxin" that drives unwillingly that host to a water spot so they can "hatch" out and reproduce in the water before the "offspring" finds a new host and re-enacts the cycle!
It takes many species to make a world!!
