I find the bugs on the windshield to be an interesting assessment.  The
main question would be whether the flora of the surrounding area has
changed.  One must keep in mind the food source for those bugs.  If the
food source was weeds or native plants, and such plants have been eliminate
due to conversion to corn or some other crop, especially with associated
herbicide use, then one would expect to see a decline in those species of
bugs irrespective of other factors.

I'm not suggesting that pesticides are not involved, just that one must
also keep other factors in mind.

Has anyone on the list observed such a decline in windshield bugs
independent of the loss of host flora in the surrounding area?
