In June my wife, daughter, and I took a road trip from Hanover, NH to Huntsville, AL. On the way we traveled nearly the length of Vermont and through parts of NY, PA, MD, WV, VA, and TN. Along the roadways we saw places that were profuse with wildflowers. Many of these areas appeared to have been deliberately seeded (I could be mistaken). Very Beautiful.
In Huntsville, while unloading the car I noticed the front of our car was covered with the remains of hundreds of insects. I could identify some as grasshoppers, butterflies, moths, dragonflies, wasps, and bees. Big fuzzy bees, blue bees, honey bees, little black bees, and others.
I had parked the car where we could see it from our second floor room. A short time later I saw a crew of about eight small birds working and pecking on the front of the car, some even appeared to be behind the grille. When we went out later that evening there were no identifiable insect parts on the car, just smudges and smears. I wonder now if our car was cleaned by birds at the four other motels that we stayed at on our way. While in Huntsville for several days we noticed birds cleaning cars in parking areas. This was our first road trip in the Eastern US.
Now, I think it isn't such a good idea to have so many flowers along highways.
