Abstract
A histological description is given of the ommatidium of the corn earworm, Heliothis zea (Boddie). The cornea has the configuration of an achromatic doublet, and the crystalline cone of a field lens, which is coated in the night-adapted eye with a quarter-wave antireflection dielectric. All morphological units fit the theoretical configuration to be expected of a mosaic optic-electromagnetic thermal radiometer. There is a fast daylight-adaptation to ultraviolet and a lack of stimulated flight in an activity cage when moths are subjected to shortwave ultraviolet (2537 A). It is concluded that the compound eye is a high absorber of far infrared radiation and of such a configuration that it could orient to hot or warm spots of longwave infrared radiation in total darkness.
