Help Requested

I am looking for help in finding larvae if a "plume" moth which is very rare (we think) in Yorkshire. The moth is called Capperia britanniodactyla. This is one species the bird club members who work upland cloughs, quarries and heaths will be likely to find. Its very easy to recognise and you are very unlikely to mistake anything else for it. I would be grateful for any records of this species, with GR please and a short description of the habitat and numbers of larvae or pupa. Rather than duplicate images and descriptions, all you need to know about what to look for and what the moth looks like are at http://calderdaleinvertebrateforum.blogspot.com/ If you can find this species it will give you a cracking record for Yorkshire lepidoptera and help me with building up my local lepidoptera records.
