How funny. I spotted my first one today as well. It was on my grapes, which is one of their favorite foods.
I know that is a VERY common belief- that cold winters mean less insects the next year. I know most people believe that and I hear it all the time. It also makes good common sense that a harsh winter would result in a substantially higher mortality rate for insects. But I just am not sure that it is true, and every spring and summer following a harsh winter I pay close attention and have never detected much if any reduction in inspects. I would be interested in seeing if any real studies have been done or if this is just another mistaken believe based on beliefs instead of empirical evidence. I’m sure I’ll be in the minority in questioning this since it is a long held belief and passes the common sense test. Perhaps over thousands or even millions of years insects have developed an ability to survive extreme winter temps. Maybe not. I just know that my garden doesn’t have less insects after harsh winters, I see just as many fire flies and mosquitoes, and Japanese beetles are just as plentiful in my experience.
