I found this funky-looking caterpillar yesterday morning. It is from The Vapourer aka the Rusty Tussock Moth (Orgyia antiqua). The caterpillar looks a bit scary with its long hairs and red & yellow spots, but actually the hairs on this species are not irritating (to people at least). They are usually in birch or hazel trees, or other deciduous shrubs, but this one was in one of the flower beds. The moth is fairly dull,;chocolate brown with a white spot on each wing, but interesting in that, like the Winter Moth, the female is flightless.
