Under a magnification of only 28X, this scanning electron micrograph (SEM) depicted some of the exoskeletal morphologic characteristics displayed on the head region of an unidentified beetle found deceased in the suburbs of Decatur, Georgia. In this particular view, the proximal aspect of what is believed to be one of the insect's two maxillary palps is displayed, at a point where the palp attaches to the maxilla. The palps act both as feelers, which means that they're sensorial in nature, as well as organs of food manipulation. The beetle is able to use these palps to position its foods in the most opportune position for chewing, and grasping with its mandibles. See PHIL 10062, 10064, and 10065, for addition views of this structure.
