Beautiful Cinnabar Moth
A Day-Flying Moth
A not uncommon sight to see is that of a fluttering and bobbing butterfly dancing above fields of flowers and weeds.
Look closer at that butterfly though, that beautiful red and black butterfly may not be a butterfly at all, it may just be a Cinnabar Moth.
The Cinnabar Moth is named after the mineral, Cinnabar, due to the red color on its wings. Another name for Cinnabar is red mercury sulfide or simply mercury ore.
It is commonly used for jewelry.

What They Eat
Cinnabar Moth caterpillars use the Senecio plant family as foodplants. Because they are voracious eaters, they were introduced to control ragwort and Tansy in some areas, including the Western US, especially the states of Washington and Oregon. This is called biologically controlling the pest plants. Since Cinnabar caterpillars eat so much, they can decimate entire areas of weeds, and then they may even turn on each other if there's nothing else to eat.
