Ragwort in Flower With Cinnamon Moth Caterpillar

I came across some wildflowers growing and in bloom on some waste ground not far from the Royal Armouries museum here in Leeds.

This one in the picture is the Ragwort, a distinctive yellow flower and on this plant was a yellow caterpillar with dark bands, the cinnamon moth caterpillar. Lots of insects and bugs like the ragwort and when in flower the cinnamon moth is quite common on this plant.
