BYM - that is the one I used! It was a bit off putting to start with because I couldn't understand what to do, and it seemed ever so technical, but then I got the hang of it and became quite awestruck with the amount of information on it, as I realised how many people around the world take the time to engage with this, and to record and upload songs and calls. Its now in my favourites.
I looked up the Lime Hawk moth (not thinking, I was expecting it to be lime green....) and its strangely familiar, I think I must have seen it somewhere. Lime trees are probably my favourite tree, I love the smell of the blossom. Tilia is a favourite infusion here, our neighbours love it as a relaxing drink in the afternoon or evening and use it for sore throats; so we do that as well now. They have a magnificent tree and gave us a big bag of blossoms; in fact when we were house hunting one of the old houses, with elderly occupants, had a bedroom full of drying blooms. Its nearly 4pm, guess what I am going to do now!
