| + | The adult fluke is plump and cylindrical (unusual for a [[Trematodes|trematode]]). It attaches to the wall of the rumen without causing serious damage. The eggs are like those of [[Fasciola hepatica|''Fasciola'']], but are colourless, and have long filaments present at the poles. |

| The intermediate hosts are water snails, and these shed '''cercariae''' which later form '''metacercariae''' on vegetation. | | The intermediate hosts are water snails, and these shed '''cercariae''' which later form '''metacercariae''' on vegetation. |

− | Disease occurs if metacercariae are eaten in large numbers. Enteritis and diarrhoea result when immature flukes migrate along the small intestine, (where the metacercariae excyst) towards the rumen. | + | Disease occurs if metacercariae are eaten in large numbers.
