Found an Elephant Moth caterpillar on the path in the garden. An amazing caterpillar, large and brilliantly marked. The caterpillar would let you turn it upside down, always flipping back uprightas I tried to draw it. When handled it withdrew it's head back into itself to inflate the eyepatch segment, perhaps to look more like a snake? Released it onto some willow-herb by the pond.
Other natural history news: Saw two barn owls hunting last night, one carrying a vole, and saw an otter dead on the roadside towards Somerton.
