Crouching forward and downward on her forelegs, this image depicts a lateral view of a feeding female Anopheles quadriannulatus mosquito. This specimen had landed on a human skin surface, and was in the process of obtaining its blood meal through its sharp, needle-like labrum, which it had inserted into its human host. Note the red color of the labrum, as it was filled with blood, and the bent, retracted labium, which normally, ensheaths the sharp labrum when it’s not in use. Also note the red-colored abdomen, filling with its blood meal contents. So full, in fact, that a droplet of excess blood had been extruded from the abdomen’s distal tip. As a member of the A. gambiae species complex, A. quadriannulatus is a known vector for the parasitic disease malaria.
