Life cycle
Dictyocaulus viviparus is ovi-viviparous and gives birth to eggs which are coughed up and eaten. These eggs hatch in the digestive tract and are then excreted live. They take advantage of sporulating Pilobilus fungi for dispersal.[3] When eaten, the larvae chew through the intestinal wall to the mesenteric lymph nodes. From there, they travel to the lungs via circulating blood and/or lymph.[4]
