Caption:
At a magnification of 161X, this 2005 scanning electron microscopic (SEM) image depicted a view of a compound eye and mouth region on the head of an unidentified green-colored, flying insect, found outside on the ground in the Decatur, Georgia suburbs. An insect’s compound eye is really made up of many repeating units known as ommatidia. Though each of these visual mechanisms functions as a separate organ, together they provide the organism with a compound picture of its environment. Due to what is referred to as the flicker effect, the compound eye is made very sensitive to movement, with each of the ommatidia turning on, and off as objects pass across its field of view. The bilateral anatomical placement of the insect’s eyes provides the insect a very wide range of visual sensitivity.
