To add to that, as cities benefit from close proximity to food and often came to be a city because they acted as ports for food distribution, cities tend to spring up on what was arable land, further destroying insect habitats and bringing that light pollution to the areas (possibly) best suited for insects. Although I'm not sure I entirely agree with your premise. As a Canadian, the lands on the Canadian Shield (a rock formation that spans across most of Canada's north) are famous for their dense insect population. The rock does not make agriculture viable there at all, but it is a great place to be an insect.
