Under a moderately high magnification of 184X, this scanning electron micrograph (SEM) revealed some of the ultrastructural morphology located on the head region of an unidentified white moth, which had been found deceased on the ground in the suburbs of Decatur, Georgia. In this particular view, what appears to be 'hairs', was actually a number of exoskeletal sensorial structures known as 'setae', located atop the insect's head. You'll also note the rows of 'scales' buried amongst the setae. Both the scales and setae are composed of the same chitinous material.
