Does an area infestation of crane flies indicate any type of weather change?
The good news is that the infestation is not indicative of any weather change. The bad news is that the infestation is not going to change, either. Since the European crane fly immigrated to your area of the Northwest, turf and pastures have been providing free lunches every spring in larger and larger parts of your state. These insects do not bite and are primarily a nuisance when found in large numbers. Spraying has little effect on the population; adults will fly in from other areas and are most common from late September through November.
