The
cinnabar moth,
Tyria jacobaeae, was released over much of New Zealand from 1929–1932 in an attempt to control ragwort, but the moth established good populations only in parts of the southern North Island. In the 1980s, a redistribution programme saw populations become more widespread, but many people still have no idea of the identity of this spectacularly coloured moth.
The moth's host plant, ragwort, has reached far beyond the farmland where it used to be a major weed (and still is in some areas), but biological control agents often have an extraordinary ability to locate their hosts. This cinnabar moth was fluttering around outside Iron Gate hut in the Ruahine range a few days after Christmas 2011.
