This 2006 image depicted a female Aedes aegypti mosquito as she was completing the activity of obtaining a blood-meal from a human host through her fascicle, which she'd begun to resheath in her labium. Both structures are part of her feeding organ known as the proboscis. 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 it filled with blood, the abdomen became distended, stretching the exterior exoskeletal surface, thereby, causing it to become transparent, allowing the collecting blood to become visible as an enlarging intra-abdominal red mass.
