The mosquito pictured here in this 2005 photograph, was until recently known as Aedes japonicus, and is now labeled Ochlerotatus japonicus. This particular specimen was a member of the Notre Dame colony. Oc. japonicus was initially collected in the United States in New York and New Jersey, in 1998.Created: 2005

This Aedes aegypti female was from a strain of mosquitoes named LVP-IB12, an acronym representing the fact that these mosquitoes were derived from the Liverpool strain (LVP), and that they were inbred 12 times (IB12), in order to create a more homogeneous genotype. Also, of great importance is the additional fact that this specie is being used in the A. aegypti genome sequencing project. Though the mosquito’s geographical origin is not known, it is believed to be somewhere in Africa.Created: 2007

This 2006 photograph depicted a female Aedes aegypti mosquito while she was in the process of acquiring a blood meal from her human host, who in this instance, was actually the biomedical photographer, James Gathany, here at the Centers for Disease Control. The feeding apparatus consisted of a sharp, orange-colored fascicle that was covered in a soft, pliant sheath called the "labellum while not feeding. The labellum was shown here retracted as the sharp "stylets" contained within pierced the host's skin surface, thereby, allowing the insect to obtain its blood meal. The orange color of the fascicle was due to the red color of the blood as it migrated up the thin, sharp translucent tube. Note the distended abdominal exoskeleton, which being translucent, allowed the color of the ingested blood meal to be visible.Created: 2006

The labellum was shown here retracted as the sharp "stylets" contained within pierced the host's skin surface, thereby, allowing the insect to obtain its blood meal. The fascicle was composed of a pair of needle-sharp stylets. The larger of the two stylets, known as the "labrum", when viewed in cross-section takes on the shape of an inverted "V", and acts as a gutter, which directs the ingested host blood towards the insect's mouth. Due to the ingestion of the female’s blood meal, the translucent abdominal exoskeleton had taken on a reddish color.Created: 2006

Though out of focus in the background, note the droplet of newly ingested blood that had been expelled, and dispersed from the distal abdominal tip merely due to over-engorgement on the host’s blood.Created: 2006
