| A magnified wasp eye |
This picture is of a Ichneumon wasp eye and antenna base base, taken by Charles Krebs at a magnification of 40x. Ichneumon wasps are parasitic wasps that lay their eggs in a host's body. Visible are dozens of tiny individual photoreceptors. The wasp combines the input from each photoreceptor to form an image. The photographer used reflected light illumination, which involves bouncing light off of an object instead of shining light through the object to illuminate it. The technique is usually used with opaque materials.
Do you know if all of the small circles on the compound eye each have different views or not?
