The top picture is of a common squash bug and the bottom an assassin bug-a 'blood sucking cone nose' specifically-both species abundant in the east. (Click on pics to enlarge). They look similar and there are many different types of both species, but generally the squash bugs are harmless except to plants while assassin bugs mostly feed on other insects. The latter can inflict a painful bite if mishandled, but ignore humans otherwise.
A friend sent me a text saying that squash bugs were frequent visitors to his house in spring, yet when he mentioned this to other people their immediate reaction was to "squish them". This reminded me of the human intolerance to insects which I attribute to ignorance and fear, and of course that same negative impulse applies to snakes and spiders and, unfortunately, to skin color, sexual orientation, religious and political differences, and many other biases equally hard to expunge from our behavior. Personally, I have grown from a child who killed insects as though they were not living things to a person who respects their right to live as much as I value my own-at least until they are attempting to harm me, at which moment I defend myself. That is a template for how I treat other human beings; do me no harm and we shall live in peace.
So insects enter our house searching for food, or warmth, or by accident, or simply because they have been sequestered in the walls all winter and now search for an exit. When a fly is beating itself against a window it wants nothing but to get out of the house; why should I 'squish it' for wanting to be free? Fear and ignorance are powerful motivators of our behavior, but not our only tools for improvement.
