Looking at the picture first, you might think that this is a colorful butterfly instead of a vibrant colored insect.
If you look at these beautiful creatures, then the assumption of moths being brown and boring will definitely be replaced by awe. These beautiful creatures with their distinctly vivid colors might confuse you for a butterfly. But don't worry we got you!
This is a cinnabar moth.
The contrasting color combination may suggest that this is a butterfly but moths often have wider, furrier bodies and their wings lay flat when they are at rest.
Their unique names come from the mineral cinnabar, which is an ore of mercury. It is extremely toxic and known for its beautiful red color. During the early days, when the concept of synthetic dyes and toxicity was not well known, cinnabar was prized in jewelry and as a pigment. These days, it's still mined and heated to create liquid mercury, but it is not used as a pigment anymore.
These little creatures are native to the British Isles and as caterpillars, they have distinct orange and black stripes before metamorphosing into their black and red forms.
It is mostly active at night but can be easily found during day time too.
One can easily find them in grassy areas and their favorite food plant is the Common Ragwort. Even though their color combination is quite consistent but you will often see a disturbance in the ratio of black and red or sometimes a hint of remarkable yellow instead of red.
