What is "triodia"

Triodia is a genus of moths of the family Hepialidae. There are seven described species found in northern and western Eurasia.

Triodia may refer to:

• Triodia (moth), a genus of moths of the family Hepialidae.
• Triodia (grass), a genus of grasses in the family Poaceae.

Triodia is a large genus of hummock-forming grass endemic to Australia; they are commonly known as spinifex, although they are not a part of the coastal genus Spinifex. Many of the soft-leaved members of this species were formerly included in the genus Plectrachne.

Triodia is a perennial Australian grass which grows in arid regions and has awl-shaped, pointed leaves. The leaf tips (high in silica) can break off in the skin, leading to infections. Leaves are 30–40 centimetres long.

Spinifex has traditionally had many uses for Australian Aborigines. The seeds were collected and ground to make seedcakes. Spinifex resin was an important adhesive used in spear-making. Smoke signals were made to communicate with families and groups a long distance away, as burning spinifex produces a strong black smoke.

The species Triodia wiseana is used for building shelters; bunched together it is used for trapping fish against creek beds. It is called baru in the languages of the Yindjibarndi and Ngarluma people, the English term is hard spinifex.
