Dicrocoelium fluke. Light micrograph of a Dicroc- oelium dendriticum fluke, a parasite of herbivores such as sheep. The testes (2 large blobs in upper frame) are seen above the ovary (small blue blob); the uterus is the mass of brown structures. The gut (blue, inverted \Y\"-shape) and yolk glands or vitellaria (black, centre left & centre right) are seen too. It lives in mammalian gall bladders & bile ducts. Its eggs pass out in its host's faeces & are picked up by snails. The larvae move around the snail's breathing passages and pass out in the snail's slime. The larvae infect ants and cause them to cling to grass until they are eaten by grazing animals. Magnification: x6 at 6x7cm size."
