Thanks so much for the tip off Dapperling - I went this morning and saw them, then out of curiosity picked one and had a nibble at it.

In one of those message in a bottle tv show coincidences I then walked along the footpath between Ightenhill and Cornfield Ildest for the first time and found my own little group of them towards the grove end.
All except one.
