large intestine
The adult form of all strongyles (large or small) live in the large intestine. Adult strongyles produce eggs that are passed in the feces, thus contaminating the environment. These eggs then develop into larvae that exist on the pasture vegetation. The larvae molts three times before it is ready to infect the horse.

What do small strongyles do to horses?
