> However, some insect species, such as houseflies and cockroaches, appear to be on the up. If this trend continues, I wonder if we will see some species previously reliant on spiders for food (birds?) switch to more cockroaches and houseflies. More likely, we will see a radical restructuring of what we consider to be "common" species. For instance, hedgehogs and sparrows - incredibly common in my own childhood - are apparently quietly disappearing from places where they were previously abundant. What will replace them?
