Hello!
I came accross your very informative site when trying to identify this strange insect climbing up the inside of our kitchen window! We live in Long Eaton, which is on the border of Leicestershire, Nottingham and Derbyshire.
We gently gathered it up and let it go into the back garden, which is quite overgrown, so a haven for insects! I do hope it survives ok! It was a very mild day, but I don't know where it had come from...I've never seen anything like it around here before!
I have entered the details on the survey section of this site, and noticed that it hasn't been spotted too frequently outside of Essex!
Good Luck in all your endeavours!
Maria Lawrence
