Story: Poisonous plants and fungi

Ragwort plant and cinnabar moth

Ragwort plant and cinnabar moth

Ragwort is a highly toxic pasture weed, causing liver damage in cattle and horses. The cinnabar moth was introduced in 1929 as a biological control against the plant. Over the years its caterpillars, which feed on ragwort leaves, have managed to control the spread of the plant in some parts of New Zealand.
