Description:

Magnified 457x, double that of PHIL 8782, this scanning electron micrograph (SEM) revealed some of the morphologic features displayed on the exoskeletal surface of an Anopheles gambiae mosquito's anterior head region. Included in this field of view was the proboscis, and two maxillary palps, the clypeus, to which the aforementioned structures are attached, and two bilateral multifaceted compound eyes. What is important in this particular view is the configuration of the "mouth", from which emanates the "labrum", which is the larger of the two sharp stylets that are used to penetrate the skin of the host when obtaining a blood meal. The labrum is a trough-like structure that guides blood up the proboscis, and into the insect's mouth.
