Just to prove my point on how I'm pretty sure on my theory.
Here is an example of my 2003 toyota celica. This is a picture of under the hood taken from today when I fueled up. Right under the huge collection of black spots is my air conditioner pulley and the direction of the belt going around the pulley flings up moisture/dirt/dust debris.
The underside of the hood has never been washed since new. (commuter car) I have lived in climates from 38 Degrees C to -45 Degrees C with this car. So it is improbable for any bug to have lived in the same spot for the past 11 years and survive these climates not to mention underhood temperatures.
I'm confident with my original post and hypothesis.
So my theory that is backed up with evidence is the one I'm going to stick with.
