AboutThe cinnabar is a moth of rough grassland and hedgerows, gardens and waste ground, where the black-and-yellow-banded caterpillars feed on common ragwort, other ragworts and groundsels. Adults are on the wing during the summer, flying in the sunshine, but also at night. They are easily disturbed, fluttering up from their feeding plants. The caterpillars pupate in autumn, spending the winter as cocoons on the ground, before emerging as moths the following summer. The bright colouring of the adults and caterpillars warns predators that they are unpalatable, having ingested the poisonous ragwort plants.
How to identifyThe cinnabar is slate-black with two red spots and two pinky-red stripes on the rounded forewings. Its hindwings are pinky-red and bordered with black. It can be distinguished from the similar burnet moths by its broader wings and red bars instead of spots.
Did you know?The cinnabar is named after the red mineral, Cinnabar, an ore of the metal Mercury.
