This isn’t actually a bad omen. It’s actually better this way as things that were sticking to windshields were pests on crops. So fewer is actually better for food stock. That’s kinda what the farmers are trying to head towards. There used to be a lot of insects. There were also many many shortages on farms as a result.
Complete nonsense. Mosquitoes, flies, bees and wasps are not pests on crops. Quite the opposite in fact, as they are all crucial for the pollination process.
