I was surprised to find this very striking moth caterpillar (Pale Tussock, Calliteara pudibunda) inside an inverted wheelbarrow in south east Wales (elevation approx 1000 feet, 300m). I only had an old style mobile phone with me, so it’s a poor image. A Google search for information and photos is here. This website has very good photos, and the adult moth is also impressive. It seems the species is “fairly common” in England and Wales, but a sighting made it into a local newspaper (South Wales Evening Post, with incorrect adult photo). When moving, black markings can be seen between the bright yellow segments, along with what looks like an erect red “tail”. I moved it to a safer place while wearing gloves, just as well because handling can cause skin problems.
