Recently, reports of insect declines prompted concerns with respect to the state of insects at a global level. Here we present the results of long-term insect monitoring from two locations, De Kaaistoep, and nature reserves in Drenthe, both in the Netherlands. We report the trends in beetles (Coleoptera), macro-moths (macro-Lepidoptera), caddisflies (Trichoptera), lacewings (Neuroptera), mayflies (Ephemeroptera) and true bugs (Hemiptera), using light traps, and ground beetles (Coleoptera: Carabidae), using pitfall traps. Based on data from light traps, macro-moths, ground beetles, and caddisies have declined in the mean number of individuals counted per evening, with annual rates of decline of 3.8, 5.0 and 9.2% respectively. Other orders appeared stable (true bugs) or had great uncertainty in the trend estimate (lacewings and mayflies).
