I found 2 eggs this morning that I am 99+5 confident were laid by her - the one beside her in this photo and one where she was resting last night, and Icollected them as I had good success raising anthelas form eggs last year. Will try and take some photos in daylight tomorrow and post. The moth was still on the mesh curtain until mid afternoon and I thought she would probably stay until tonight and maybe lay some more eggs but she disappeared. I suspect she flew when the afternoon sun reached her rather than she was take by a bird.
