Bugs on the windshield!  To most people that means poor driving vision and the need for strong windshield cleaner fluid.  The pest management specialist may view the situation differently.

The presence of large numbers of insects on the windshield might signal an approaching pest problem.  For instance, large numbers of moths on the windshield on a quiet night may mean that it's time to scout corn for cornborer eggs and larvae.  The same might be true for moths of fall armyworms or sod webworms.

Entomologists also use light traps or pheromone traps to collect adult insects to determine the time for scouting operations.  Philosophers still debate whether the chicken or the egg came first.  Entomologists, on the other hand, know that after you see the moth the larvae can't be far behind.
