A bit of what we see happening on the farm fields. Due to new government regulations for spraying crops, we now have to scout fields for larvae of different species in the fall, instead of waiting to find the adults in spring. I have noticed a lot of grubs from different species of beetles, but especially Japanese beetles ( these grubs are the ones often  in your lawn). We also see cutworms etc buried about 6" deep, they will go deeper if it turns cold, but currently in the open fields with hardly any frost in them, the soil will warm up early if it gets sunny, and if not more snow arrives, the fields will also dry up quicker, thereby bringing bug populations to the top. So, if nothing much changes the rest of this winter I would think early ice out and warmer then usual temps may very well may mean early bug cycles.
