Earlier quoted context omitted.
Perhaps, but the difference between butterflies and mosquitoes isn't really in damage to the food (virtually zero in both cases)... it's in the fact that butterflies perform a service (pollination) for the flowers. Mosquitoes quite literally live and die by the lightness of their touch; compare the survival rates of human-feeding mosquitoes (not 100%, but not far off) and human-feeding horseflies (0%).
When I show moon, look at the moon, not at my finger (another quote).
