The G.M.S., which I take part in, involves putting our trap out every week, on the same night where possible, in the same position, from the beginning of March to the beginning of November. Comparing year on year catches for comparison becomes possible.
The last two years are:
Species 165 172
Total Moths 2,680 1,269
Species have increased very slightly but the total is down just over 50%.
A large amount of the missing moths are accounted for by vast reductions in some of my gardens more common species. See below;
Dark Arches -75%
Large Yellow U/W -65%
Heart and Dart -65%
Common Rustic -83%
Does these figures look familiar to other mothers or has it just been a poor year up here.
