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.  You’ll note the feeding apparatus consisting of a sharp, “fascicle”, which while not feeding, is covered in a soft, pliant sheath called the "labellum”, which is seen here retracted, as the sharp “stylets” contained within pierced the host's skin surface, as the insect obtained its blood meal. The fascicle is 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.

Dengue is a viral disease transmitted by urban Aedes mosquitos, principally A. aegypti, a species found living in close association with humans in most tropical urban areas. Mosquito biting activity is greatest in the morning for several hours after daybreak and in the late afternoon for several hours before dark. It may feed all day indoors, in shady areas, or when it is overcast. This mosquito breeds in artificial water containers, such as discarded tires, cans, barrels, buckets, 55 gallon drums, flower vases, and cisterns, all frequently found in the domestic environment. Since 1980, the incidence of dengue has increased dramatically in tropical countries worldwide, with endemic and/or epidemic virus transmission documented in most countries of the Caribbean Basin, Central and South America, the Pacific Islands, Asia, and Africa; many countries have had multiple outbreaks. Epidemics are frequently
