Comparison of moth catches

As promised in the previous post, I have been comparing the catch from one of last nights traps with that from the same trap in the same place on 6/12/16. I realise that this is completely unscientific and no conclusions can be drawn. The fewer species and smaller numbers could be due to weather conditions, although last night was quite mild and still. Note in diary to trap same place same time next year.
