Teacher. Frank Hadley Collins, Dir. Cntr. for Global Health and Infectious Diseases, Univ. of Notre Dame With a newly-obtained fiery red blood meal visible through her now transparent abdomen, the now heavy female Aedes aegypti mosquito takes flight as she leaves her host's skin surface. In this case, what would normally be an unsuspecting host was actually the CDC's biomedical photographer's own hand, which he'd offered to the hungry mosquito so that she'd alight, and be photographed while feeding. After having filled with blood, the abdomen became distended, stretching the exterior exoskeletal surface, causing it to become transparent, and allowed the collecting blood to become visible as an enlarging intra-abdominal red mass. The wings seem to be working overtime in order to keep her aloft. Dengue is a viral disease transmitted by urban Aedes mosquitoes, principally A. aegypti, a species found living in close association with humans in most tropical urban areas. Mosquito biting acti

This is an enlarged view of a Culex quinquefasciatus mosquito that had landed upon the skin of a human host, as was about to insert its needle-sharp proboscis through the skin, which would enable it to obtain its blood meal. C. quinquefasciatus is known as one of the many arthropodal vectors responsible for spreading the arboviral encephalitis, West Nile virus (WNV) to human beings through their bite when obtaining a blood meal.
