The Scarlet Tiger is a very local species of moth, found mainly in the southern England. Normally I find them on Moor Copse, a nearby nature reserve with a small river running through it, but occasionally they do roam further afield (or perhaps get blown?) and this year I have seen one twice in my back garden in Tilehurst. My neighbour was so surprised that he rushed out and took photos of it when it landed next to his pond 🙂
The larvae feed on Comfrey, Nettles & Brambles and the adults are highly aposomatic (having warning colours to deter predators).
