Love has its own instinct, finding the way to the heart, as the feeblest insect finds the way to its flower, with a will which nothing can dismay nor turn aside.
— Honore de Balzac

A fly may sting a stately horse and make him wince; but one is but an insect, and the other is a horse still.
Samuel Johnson insects quote

We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.
— Charles Darwin

The butterfly's attractiveness derives not only from colors and symmetry: deeper motives contribute to it. We would not think them so beautiful if they did not fly, or if they flew straight and briskly like bees, or if they stung, or above all if they did not enact the perturbing mystery of metamorphosis: the latter assumes in our eyes the value of a badly decoded message, a symbol, a sign.
— Primo Levi

a man thinks he amounts to a great deal but to a flea or a mosquito a human being is merely something good to eat
