Healthy skeptisicm is a good thing.I always get a little irritated when I see words like Apocalypse and Armageddon used in articles, particularly when linked to ecology. The first thing to consider is the quality of the evidence, which isn't really that impressive, its suggested that we have only identified around a fifth of the species and we have very poor baseline data. One of the problems in the study of insects is the degree of specialisation in some species, its likely that small environmental changes and shifts towards monoculture may have a massive effect on some species. I know people have outlined their own experiences but something I haven't seen is a mention of huge swarms of some insects, in the UK we were swamped with continental ladybirds last summer, which are of course predators. There have also been significant recovery of pollinator species despite attempts by some groups to use the decline to ban certain insecticides, with little evidence. This is one of those issues that need to be investigated properly without it drifting into other alarmist stories. I say this because if there really is a mass insect extinction taking place the effects that this would have on the ecosystem would make every other alarmist message irrelevant, the effect on agriculture really would make this a global disaster. The first link discusses some of the research and the second tries to bring a bit of realism to the discussion.
