Why the Mosquito?

A pentimento ... is an alteration in a painting, ... showing that the artist has changed his mind." I recalled this art term this morning from the dim depths of the past. I looked it up in Wikipedia and found that I had remembered the spelling almost exactly, give or take a vowel.
. Moving on to a seemingly unrelated subject, but comparing Creation to a work of art: I've always wondered about the purpose of the mosquito in the scheme of Nature. All I can think of is that it must be somebody's food (inasmuch as we appear to be its favorite food). We have adopted every reasonable measure to keep them away from us during mosquito season. This year that season has broken all records, continuing even to this week, about a month and a half past normal. This great continuous hatch is probably due to the "monsoon" we've had for most of the last three months. I despise these flying, humming annoyances so much I was thinking of building one of those bat houses in order to enlist the aid of our furry winged friends in doing them in.
. Today I realize that they are actually a mistake in the Creation.... . That statement is hard to prove except by inference, but I have it figured out. God never goes back -- being the Supreme One, after all. But God felt really bad about going too far in creating things that make humans miserable. So what he conceived of next is, by analogy, a pentimento. He gave us CHOCOLATE to try to make it up to us!
