New species - but not welcome

Yesterday I found a ladybird in the lounge and it was not obvious to me what sort it was. Investigation showed it to be a Harlequin ladybird - an invasive and destructive species from Asia. According to some sources this is very bad news for some of our domestic ladybirds and other beetles. It is spreading North and West and it is not new to the Midlands. Having checked the pictures I remember some larvae that I found last year which may be the Harlequin's larvae. I will need to find the photographs I took at the time to be sure. I found a ladybird outside today and I am pleased to say it was a 7-spot.
