Tussock
Definition:
(n.) A tuft, as of grass, twigs, hair, or the like; especially, a dense tuft or bunch of grass or sedge.
(n.) Same as Tussock grass, below.
(n.) A caterpillar of any one of numerous species of bombycid moths. The body of these caterpillars is covered with hairs which form long tufts or brushes. Some species are very injurious to shade and fruit trees. Called also tussock caterpillar. See Orgyia.
Example Sentences:

(2) An unusually heavy infestation of the tussock moth resulted in a high incidence of symptoms affecting the skin and mucous membranes of those exposed to high concentrations of particulate matter of this insect.
(3) Tall grass tussocks used as shelter by the latter have been grazed down by the ruminants, and replaced by "marsupial lawns" or xeric spinifex, depending on locality, thereby improving the food supplies for the plains kangaroo and the hill kangaroo, respectively.
