Diseases of cattle, sheep, goats Diseases of cattle, sheep, goats and swine diseasesofcattle00mous Year: 1920 Fig. 200.—Adult male of the grass tick. Length, th of 1 inch. Fig. 201.—Adult female. Length, |th of 1 inch. species of ticks attack some ' host ' or animal, either beast, bird, or reptile, to which they attach themselves by the ' rostrum ' or beak, and become greatly distended by suction of the host's blood. When replete they fall to the ground—if a larva or pupa, in order to undergo its metamorphosis to the next stage of its existence, and afterwards seek a fresh host; if an adult female, to lay its eggs amongst herbage. The adult male is not capable of distension by suction, though it equally attaches itself to a host. After undergoing metamorphoses, grass ticks, with the exception of males, are light in colour, soft and lethargic, and remain concealed for some time while recovering strength before seeking a fresh host. Professor Neumann alludes to the fact that a fresh host is sought by ticks three several times during their existence.
