I have also remarked on diminishing windshield smears over the last decade
or more driving on the prairies at night in summer. Even in the forested
areas, windshield bugs seem to have diminished.
Maybe bugs are smarter about cars and headlights now? Maybe over a few
generations and 90 years cars killed all the genetic types susceptible to
headlight attraction and the absolute numbers are unchanged? But, more
probably our headlights are better focused and less attractive to all bugs
in the area? Sounds plausible.
There are other interesting puzzles out there. As a result of minor
temperature changes in our ever changing climate and significantly
increasing carbon dioxide released from permafrost by interglacial warming
the climate cycle and to an unknown but indubitably significant extent by
human activity like production of cement and electricity production that
comprise 40% of US CO2 output we are seeing a change in the plant growth
planet-wide, both in area colonized and plant composition.
Many bugs eat plants and/or plant secretions. We are reportedly seeing a
change in the nutrient proportions in plants, due to increased availability
of their major nutrient, carbon dioxide, and less need to sacrifice of
water to/from the air through stomata. This means less water transport
from the roots with minor nutrients and a change in food value to humans
and maybe bugs?
