Magnified at 500X, this scanning electron micrograph revealed some of the exoskeletal ultrastructural morphology located on the head, or cephalic region of an unidentified mosquito found deceased in the suburbs of Decatur, Georgia. Note the two bilaterally situated 'scapes', which act as the first antennal segments, that may be seen in greater detail in PHIL 10553, 10554, and 10555. The right compound eye is evident at the top of the image, and appears to be constructed from shriveled grapes, which are actually ommatidia that were deformed in the specimen fixation process.
