By far the easiest insect to photograph, they just fly right up to you! They bring itching, hives, and swelling and they make the most annoying high-pitched sounds as they fly around your head. My favourite nature and science writer, David Quammen, writes that the mosquito is a fierce defender of its turf. The fact that we still have large tracks of equatorial rainforests is due to fact that humans fear the disease-bearing, blood-sucking mosquito. Likely the tropical forests of the world would have disappeared a century ago if malaria and yellow fever had not kept settlers away. So it appears that this human parasite has some good after all.
