The curse of farmers, because it is so poisonous to animals, particularly horses, ragwort is one of our top ten pollinators, so, hooray for ragwort!
It is beloved of the cinnabar moth caterpillar. Last year I saw a single yellow and black stripy caterpillar, but this year I am pleased to say there are masses. And they are making short work of the ragwort plants, which is precisely why they were introduced into the country, in order to control the plant!
The good news is that the caterpillars will eventually morph into one of these beauties!
