The 10 species with the largest falls in numbers of individuals compared to the 10 year average are Brimstone (-176), Uncertain (-198), Shuttle-shaped Dart (-255), Lunar Underwing (-283), Common Footman (-316), Setaceous Hebrew Character (-390), Square-spot Rustic (-411), Large Yellow Underwing (-419), Vine's Rustic (-435) and Heart and Dart (-1409).
Even so, these all still occurred in fair numbers. There is also a set of once regular species which showed large percentage falls in 2008. The worst are Dark Sword-grass (86), Marbled Green (86), March Moth (86), Common Wainscot (86), Centre-barred Sallow (86), Canary-shouldered Thorn (87), Lunar Marbled Brown (88), Turnip (90), Green Silver-lines (94) and Beaded Chestnut (95).
If you remove the two migrants there are another 71 species which fell by over 50%. Hopefully this is partly because the weather was poor for catching moths. Otherwise it's not looking great near the bottom of the food chain.
